BARREL Status Report #12
August 17, 2016
BARREL Flight 4B was terminated this morning at 0350 UT. The balloon started with a nice southerly trajectory, so we thought we might get a long flight out of it. But, it took a sharp turn to the west right after sunrise and had to be cut down as it approached the mountains. Despite the relatively short flight, we caught all of the RBSP conjunction we were targeting, and even had some substorm activity. We saw a very bright relativistic precipitation event which may have been associated with that substorm. The payload was recovered in very good shape earlier today. Note that this payload was also carrying the Univ. of Houston TEC experiment. We’re excited to see if they saw any change in total electron content due to the energetic precipitation!
The Van Allen Probes EFW team is now requesting playback of burst data from our first flight and they are planning data collections for the next conjunctions. We will not be launching on Thursday due to the predicted flight trajectory (climb out is mostly west which shortens the flight substantially). So, the next launch attempt is likely to be on Friday. I’ll send another update then.
