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.
145 sunspots are now visible. NOAA has upped the likelihood of a M class flare to 50% and a 5% chance of an X class flare. The Evil Twins are slowly making their way around. There was an M class flare earlier, not sure if it was the evil twins but it potentially caused some radio trouble. I'm not sure if it was the twins and kind of doubt that it was geo-effective as the prediction for storms is still around 10%.
Kp is quiet kp = 1 with a 24 max of kp = 1
Bz = 0.3 nT north
Btotal = 3.8 nT
There are no large coronal holes on the sun
AE: There is extended activity (albeit <500 nT) starting today right before 1000 UT and continuing till after 1400 UT.
Dst: If we define a storm as something that has a min. Dst < 10 nT... then we've seen something but really no. Nothing, it's really really quiet.
Update on KML files:
I've added a new feature. The balloons turn red when they are below altitude! I've updated 1B and 1D and am in the process of updating 1M.
Update on events:
We're starting to try to have a science discussion on the blog, please feel free to comment, submit data. If you want to submit data/plots to the blog just e-mail me, but make sure to state that it's okay to post, otherwise I'll error on side of caution and not post it.
We saw two more really small events
1) 1D saw something at 0448 UT on Jan 11th 2013 (almost the same time as the one on the 9th)
2) I think just 1D again, but at 1212 UT when there was quiet a lot of activity in the AE index. Warren has provided the spectrum data for us.
