BARREL Daily Update Jan 31st 2014

Hi all, 

There was a large(ish) flare that occurred right as the lunar transit ended. It also happened to produce an asymmetric halo CME which we should see a glancing blow on Feb 2nd. This flare came from our favorite sunspot 1967. 

If you look at the wind maps you can see that they are becoming a bit more chaotic. 2L has taken an interesting path and may start going around Antarctica again. 

Ground Weather:
Temp.: -10. C
Wind speed: 6 knots

Halley 6: 
Temp.: -7.2 C
Wind speed: 15 knots
