New findings based on a year's worth of observations from NASA’s Van Allen Probes have revealed that the ring current – an electrical current carried by energetic ions that encircles our planet – behaves in a much different way than previously understood.
The ring current has long been thought to wax and wane over time, but the new observations show that this is true of only some of the particles, while other particles are present consistently.
Using data gathered by the Radiation Belt Storm Probes Ion Composition Experiment, or RBSPICE, on one of the Van Allen Probes, researchers have determined that the high-energy protons in the ring current change in a completely different way from the current’s low-energy protons.
Such information can help adjust our understanding and models of the ring current – which is a key part of the space environment around Earth that can affect our satellites.
The findings were published in Geophysical Research Letters.
“We study the ring current because, for one thing, it drives a global system of electrical currents both in space and on Earth’s surface, which during intense geomagnetic storms can cause severe damages to our technological systems," said lead author of the study Matina Gkioulidou, a space physicist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. “It also modifies the magnetic field in near-Earth space, which in turn controls the motion of the radiation belt particles that surround our planet. That means that understanding the dynamics of the ring current really matters in helping us understand how radiation belts evolve as well.”
The ring current lies at a distance of approximately 6,200 to 37,000 miles from Earth.
The ring current was hypothesized in the early 20th century to explain observed global decreases in the Earth’s surface magnetic field, which can be measured by ground magnetometers. Such changes of the ground magnetic field are described by what's called the Sym-H index.
“Previously, the state of the ring current had been inferred from the variations of the Sym-H index, but as it turns out, those variations represent the dynamics of only the low-energy protons,” said Gkioulidou. “When we looked at the high-energy proton data from the RBSPICE instrument, however, we saw that they were behaving in a very different way, and the two populations told very different stories about the ring current.”
The Van Allen Probes, launched in 2012, offer scientists the first chance in recent history to continuously monitor the ring current with instruments that can observe ions with an extremely wide range of energies. The RBSPICE instrument has captured detailed data of all types of these energetic ions for several years.
“We needed to have an instrument that measures the broad energy range of the particles that carry the ring current, within the ring current itself, for a long period of time,” Gkioulidou said.
A period of one year from one of the probes was used for the team’s research.
“After looking at one year of continuous ion data it became clear to us that there is a substantial, persistent ring current around the Earth even during non-storm times, which is carried by high-energy protons. During geomagnetic storms, the enhancement of the ring current is due to new, low-energy protons entering the near-Earth region. So trying to predict the storm-time ring current enhancement while ignoring the substantial pre-existing current is like trying to describe an elephant after seeing only its feet,” Gkioulidou said.
The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built and operates the Van Allen Probes for NASA's Science Mission Directorate. RBSPICE is operated by the New Jersey Institute of Technology in Newark, New Jersey. The mission is the second mission in NASA's Living With a Star program, managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The electoral map in presidential campaigns has changed quite significantly since the extremely close 1960 election, in which a young charismatic senator managed to squeak by an almost equally young incumbent vice president.
Massachusetts Senator John F. Kennedy enhanced his electoral chances by picking Senate Majority Leader Lyndon B. Johnson as his running mate, for the widely-held view that Texas’ 24 electoral votes were crucial to victory.
Keep in mind that combining the 24 votes from Texas, which the Democrats carried by a narrow margin, with the 27 electoral votes from Illinois, which Kennedy carried by an even slimmer edge, and you have an interesting scenario if the 51 votes had gone to Vice President Richard Nixon.
But then Nixon only carried his home state of California by less than one percent. However, if he had carried Texas and Illinois, his electoral votes would have put him in the White House as the 35th president.
The changing electoral map apparently consumed Lyndon Johnson’s keen political interest four years later.
As we sadly know all too well, tragedy struck on Nov. 22, 1963, and Johnson was sworn in as the 36th president.
The HBO film “All the Way,” based upon an award-winning Broadway play, is a riveting behind-the-scenes look at the larger-than-life President Johnson’s tumultuous first year in office in the wake of President Kennedy’s assassination.
Much of the film focuses on the political battle for the 1964 Civil Rights Act, which pitted Johnson against some of his old Senate allies, notably Georgia Senator Richard Russell (Frank Langella), while he sought election year compromises to thread the political needle.
Probably the best thing about “All the Way,” which by the way is a play on the “All the Way with LBJ” campaign slogan, is that Bryan Cranston, the Tony Award-winner for playing LBJ on the Broadway stage, transforms himself again, complete with Texas twang, for the same role.
Cranston’s Lyndon Johnson is brash, profane and a Machiavellian political manipulator. Oddly enough, he frets about the upcoming 1964 election, which never should have been in doubt regardless of whether his opponent would be Barry Goldwater or Nelson Rockefeller.
Though he could be tough and merciless, Johnson is also portrayed as consumed with self-doubt and a fear of political humiliation.
But mostly, Johnson demonstrates keen deftness for maintaining a high-wire act as one who followed a beloved predecessor, a status he seemed unlikely to match.
There are great scenes with a determined Dr. Martin Luther King, Jr. (Anthony Mackie), who is seen working feverishly to bridge the differences with factions in the civil rights movement who don’t quite trust LBJ, son of the South, to deliver on the big promises.
But then, Johnson is also seen as being tough on his mentor, Senator Russell, when he professes to love him more than his own father, but threatens to crush him if he gets in his way of passing civil rights legislation.
The one person on Johnson’s staff who seems to be the key to holding the President together is long-time aide Walter Jenkins (Todd Weeks), but the interesting thing is that only weeks before the 1964 election, Jenkins was arrested in a sex scandal in a YMCA men’s bathroom.
Little attention is paid to this scandal, which in the end had little if any impact on the election, but then “All the Way” has nothing to say at all about more damaging material involving former aide Bobby Baker and insider Billie Sol Estes.
The Lyndon Johnson political style seemed to assume the mantle of the take-no-prisoners posture, even when negotiating with allies. He’s quoted in the film as saying that “there’s no place for nice in a knife fight.”
An interesting part of the political equation for the looming election campaign against Arizona Senator Barry Goldwater was the fear of losing the South. Indeed, in 1960, the Kennedy-Johnson ticket carried most of the South with the exception of Florida.
“All the Way” revives memories of the serious political and moral skirmishes in the South, most notably in Mississippi where three young Freedom Summer workers were killed by segregationists.
As a result, there are potent reminders of the bitter fight when the Mississippi Freedom Democratic Party challenged the establishment at the Atlantic City convention by seeking to have their own delegates seated as part of the state’s delegation.
All in all, “All the Way,” while allowing Melissa Leo a chance to shine as the supportive Lady Bird Johnson, is nonetheless the Bryan Cranston show. Almost forgot to mention Hubert Humphrey (Bradley Whitford), who comes across as disposable to LBJ’s political ends.
Speaking of things barely mentioned, the Vietnam War is glossed over until the end credits, which serve to note that by the Spring of 1968 the war had caused many American deaths for a cause that generated widespread protests.
I was slightly more interested in the end credit note that in “facing a divided electorate and poor health” Johnson announced in March 1968 he would not seek re-election.
Senator Eugene McCarthy might take exception to that. His significant showing in the New Hampshire primary demonstrated Johnson’s vulnerability such that New York Senator Robert F. Kennedy entered the race, with Johnson shortly thereafter announcing he would not run.
“All the Way,” airing several times in late May and early June, is tailor-made for political junkies and historians for a polarized election year in which the controversial Johnson commercial about the perils of nuclear war would come off as relatively benign.

Mentoring a new generation of hunters
Question: I just took my first Hunter Education Class last week at the age of almost 60. I am interested to put my training into practice and bring my kids and grandkids into it as well.
What is a good plan to begin hunting that can include all of us, since I have never had anyone to teach me how to start? (Ken B., Palo Alto)
Answer: First of all, welcome to the exciting camaraderie of California hunters.
We can recommend several options. First, put your new Hunter Education Certificate to use right away by purchasing your hunting license and tags/tag applications. The Big Game Drawing online application deadline for elk, antelope, bighorn sheep, and premium deer tags is midnight June 2, 2016.
We encourage you to go through the application process together. It will introduce all of you to navigating the online system and may also prompt an interest in other big game hunting opportunities, such as apprentice hunts. If your grandkids are junior hunters, ages 12-17 years old on July 1 of the license year, these apprentice hunts are an excellent option for most big game.
Every hunter who annually applies for draw hunts anxiously awaits the results from the draw. Then, if successful, they can enjoy the experience of spending scout time leading up to the hunt planning for their adventure. The planning stage is an important part of the hunt you can all do together.
Don’t forget, an integral part of the hunt is sighting in your firearm or bow at the range, another activity you can do together.
Draw hunts are not your only options – wild pig tags and some deer tags are simply available for purchase. Wild pig hunting is a good introduction to big game hunting and require a tag to hunt them. However, the season is open year-round and there is no daily bag limit.
Consider hiring a licensed hunting guide. It may cost you some extra money, but guided hunts frequently give you access to private properties with higher density game populations. Guides should have expertise for the species and the area you are hunting.
Soak up everything the guide is willing to teach you. If you or your kids are successful, most guides will offer to field dress the animal for you. We strongly recommend having your guide teach you how to field dress the animal and do it yourself.
What info must be on a sports crab pot buoy?
Question: What information is required to be displayed on sports crab pot buoys? I have placed my CF numbers from my boat on mine but have read that I must also place my GO ID numbers on the buoys.
Can you please let me know what’s required for my buoys? Also, what are all of the necessary requirements for my crab pots to make them legal? (Ken H.)
Answer: No identification is currently required to be placed on the buoys of sport crab traps. However, beginning Aug. 1, 2016, a crab trap buoy must be legally marked with the operator’s GO ID number as stated on his/her sport fishing license.
Keep in mind that crab traps are only allowed in waters north of Point Arguello (Santa Barbara County), and are required to have at least two rigid circular openings of not less than four and one-quarter inches inside diameter, constructed so that the lowest portion of each opening is no lower than five inches from the top of the trap.
Starting Aug. 1, 2016, crab traps must contain at least one destruct device of a single strand of untreated cotton twine size No. 120 or less that creates an unobstructed escape opening in the top or upper half of the trap of at least five inches in diameter when the destruct attachment material corrodes or fails (California Code of Regulations Title 14, section 29.80(C)(1-3)).
Compound bow for protection?
Question: This question goes back to the special junior turkey archery hunts available prior to the start of the regular spring turkey season. I accompanied my son on one of those hunts. I was concerned about our safety because there are bears and mountain lions where we would be hunting, as well as mountain lions basically everywhere in California.
If I had had my hunting license, could I have had my compound bow on me for safety? I ask because I know you cannot have a firearm on you during archery-only seasons (I don’t have a firearm anyway), so could I have had my bow on me during the junior-only hunt? (David R., Sunnyvale)
Answer: You could have possessed a crossbow in this circumstance as long as you had a valid hunting license and tag for game that could be lawfully taken with a crossbow (such as wild pigs if they are present in the area) and you do not hunt turkey.

CLEARLAKE, Calif. – St. Helena Family Health Center-Clearlake has opened an expanded dental care suite designed with the patient experience in mind.
The bright, spacious and beautiful suite is located in Clearlake at 15230 Lakeshore Drive, Suite 105.
The new suite, located just down the hall from the previous space, has 10 operatories (up from four), a state-of-the-art Panoramic x-ray machine, welcoming lobby and entirely new equipment.
“Our goal is bright and healthy smiles,” said Mark Cooper, DDS, director of the dental service. “With the new office, we can greet patients more quickly, provide them with the care they need and send them home motivated to maintain their dental health for a lifetime.”
Five dentists, a team of registered dental assistants and dozens of patients a day could attest – the previous dental care space was simply too small.
“Over the past year we have been actively expanding the dental care service to meet growing demand, including hiring a new full-time dentist,” explained Garin Fuhriman, administrative director for St. Helena’s Rural Health Clinics. “This bigger and brighter space allows us to do what we do best: serve our patients.”
The dental care team focuses on restorative and preventative dentistry with an emphasis on patient education. Services include exams, cleanings, fillings, sealants, dentures and partials.
Intraoral cameras allow dentists to show patients exactly what is happening inside their mouths, while screens at every chair can display educational videos about oral hygiene or what is involved with a particular procedure.
The St. Helena Family Health Center Dental Care serves the whole family, including children and adults, and is open Monday through Friday.
Dental services for children and teens are also available at the Konocti Wellness Center in Lower Lake. Dental care services accepts patients with Medi-Cal/Denti-Cal insurance.
On May 24, the community members is invited to celebrate the grand opening of the new dental care suite.
From 5 to 7 p.m., individuals can tour the space, meet the dental team and enjoy food and entertainment for the whole family.
The new dental care suite is located at the St. Helena Family Health Center-Clearlake at 15230 Lakeshore Drive, Suite 105, in Clearlake. Schedule an appointment by calling 707-995-4540.
