Update Summary
It's been rainy hear and that has put a delay on our dress rehearsal at ESRANGE. That means that our first possible launch date has been delayed by at least a day.
It looks though that we may be able to get a balloon up for August 9th or 10th when we have another couple of nice conjunctions and it looks like, according to ENLIL that we may have another high speed stream event. It also looks like a there is a larger Sun spot starting to come around to the earthward side of the sun. It seems like we may be in for some good space weather during this campaign!
News from Kiruna
Ground Weather:

Temp.: 13.3 C
Wind speed: 1.2 m/s with a max of 2.3 m/s within the last five minutes or so.

Precipitation (rain): 2.0 mm
Tomorrow it appears that it will be cloudy with the chance of some rain and Saturday is likely to be rainy. The winds are looking to be high for both days as well.
Stratospheric weather:
Once we have the full weight of the payloads plus the terminate system that ESRANGE will add to our payload, we'll have a more accurate map of the expected flight paths and lengths. We do think though that the turn around winds may start to set up by this Saturday the 8th.
Payloads up: First possible launch date August 9th

News from THEMIS:
From Xiaojia - I have put together a couple of close conjunctions (in L) between three probes of THEMIS and this BARREL balloon (attached), assuming that you launch at early local morning on August 7th and the geographic location is stabilized at esrange. Currently the THEMIS Ops team are working on implementing special time-based particle burst captures (at 128 Hz) during these intervals.
News from Firebird:
Summary
Previously from Alex - Flight unit 4 is completely full from our campaign 4, Flight unit 3 is 97% full (should fill up later today). We are finishing downlinking some of our hi-res and catching up on our context data, but should be able to meet an August 7th turn around launch.

Kiruna Magnetometer: http://www.irf.
There may have been a ULF from 10 - 11 UT this morning. It also looks like there may have been a substorm or two last night. It was raining though so we have no data from. We have to analyze the data to see if we happen to catch any of the auroral that may have been overhead.

It looks like there were quiet a few nice ULF waves yesterday during the period which looked perhaps like a substorm here at Kiruna.

See you soon Vi ses snart! Chris will be joining us soon to help launch the balloons!

Hej då och bra kväll från Kiruna (Good bye and good evening from Kiruna),
Alexa and the BARREL team.
