BARREL (Balloon Array for Radiation belt Relativistic Electron Losses) is a multiple-balloon investigation that will study Earth's Radiation Belts.
Atmospheric losses of relativistic electrons play an important role in radiation belt dynamics; precipitation into the atmosphere may even completely deplete the radiation belts in some cases.
BARREL is the first NASA Living With a Star Geospace Mission of Opportunity, and will support NASA's RBSP (Radiation Belt Storm Probes) mission.
156 sunspots are now visible. NOAA increased the likelihood of a M class flare to 65% and a 10% chance of an X class flare. The evil twins have started crackling, but are only about a third of the way across the sun so still a few days away until they may become geo-effective. There have been multiple M and C class flares occurring from the evil twins sunspot! Lets hope they hold out a little bit longer.
Kp is quiet kp = 2 with a 24 max of kp = 2
Bz = 4.3 nT north
Btotal = 4.9 nT
There are no large coronal holes on the sun.
AE: It looks like we are currently getting a substorm with AE peaking about 500 nT. There were two possible small substorms earlier in the day at 0100 and 0700 UT Jan 13 2013.
