BARREL Daily Update: Jan 26th 2014

Hi all, 

We're hoping that Halley will have a launch today. Payload 2O is out on the flight line so hopefully in a few hours we'll have it up on one of the socs! There has also been a slight up tick in geomagnetic activity. We had some substorms over the night and we even had the Dst down to -28nT. Okay, sure, that isn't much, but the last time Dst was that low was back on Jan 1st. 

The sunspot region which produced the X-class flare is not back on the Earthward facing side of the sun and could potentially be geo-effective by Jan 29th. We are now seeing C-class flares (they go B, C, M, X in rising order) which is nice after a day or two of only B-class flares. Perhaps we'll have a large event by the end of the week. Fingers crossed!
