BARREL Daily Update Jan 28th 2014

Hi all, 

Sun spot 1944 is producing lots of M class flares and our balloons saw more than a few. It has also been given a new name, 1967. It appears to have decayed from what it was on the last rotation, but it's still quiet active. 

Halley is hoping to have a launch today or tomorrow. This would give us once again an array of 7 balloons. Hopefully we'll have some activity for them to see. Tomorrow is suppose to be more active than today and the 30th has an even better chance for activity. It looks like NOAA is thinking that the 30th will have a growing chance of substorm activity over the next three days. I think we should try to grab a good conjunction on at least the 30th. If this keeps going, we're going to have to work over the weekend :). 

You can see that the winds are changing. 2L looks to be starting to cut down the middle of the continent, like 1I did last year, instead of continuing around the continent like 2I or 2T this year. If you remember, this was close to the time period when we had 1G sitting almost stationary for a period of days right underneath one of the GOES footprints. Perhaps we'll get lucky again this year with a similar extended conjunction.
