BARREL Daily Update Jan 27th 2014

Hi all, 

Yesterday Halley launched 2O and SANAE launched 2D today. On another note, as we haven't been able to reconnect with 2C it is likely that it has self terminated or is terminating very shortly.

If you haven't checked out Aaron's e-mail, with this new increase, we've been able to get rid of almost all the backlog of burst data! So, if you had a time period that you were interested in, but perhaps figured wasn't as interesting as some other things in the cue... Speak up! We may be able to grab it before we overwrite. Also thanks to the EFW and EMFISIS teams in particular and the whole Van Allen team in general for getting this to work!

Sunspots 1944 and 1946 are still peaking their way around and appear to still be active! There was also a small CME which may give us a glancing blow on Jan 29th. The ENLIL models though only show a very very slight increase in density and nothing really in SW velocity. If we aren't in trouble with over writing important stuff, perhaps we should grab some burst data during this time, but I don't think it should be a high priority. There may be better stuff coming with the reappearance of these two sunspot regions, so something to keep in mind. Also If you remember there was a larger geo-effective coronal hole right after these sunspot regions. From the pictures of the backside of the sun, it looks like this will also make a reappearance. This coronal hole had SW velocities > 800 km/s, but northward Bz. Hopefully we'll be able to see some more amazing geomagnetic activity from both the sunspots and this coronal hole in a week or so's time.
