BARREL Daily update Aug. 14th 2016

Update Summary
From Robyn - I’m happy to report that BARREL Flight 4A was a success! The balloon and payload both performed well. The flight was terminated at 0540 UT because it was moving west towards lakes and mountains. It was a short flight, but longer than we expected. Most importantly, we caught the conjunction with RBSP-A that we were targeting, and we saw a precipitation event that lasted almost two hours.  A preliminary look suggests that this was bursty, most likely microburst precipitation. We’ll need to look at the data more carefully, but this looks very promising. The payload is now on the ground at 67.72N, 18.88E, and recovery prospects look good. 

I think the team will be resting for most of the day today. We expect the next launch attempt to be on Tuesday. I will send another update when we get a better look at the surface weather.

From Arlo- We have recovered the payload from flight 4A! There was some light damage to the box and handles, but the payload seems intact upon initial inspection. The recovery was smooth in an easy to reach, relatively dry area. 

News from Kiruna
Next possible launch date - Tuesday Aug 16th

Payloads up:

Payloads coming/which came down:
4A Launched: 22:24 UT Aug. 13th - 05:40 UT Aug. 14th 

News from Van Allen Probes:
EMFISIS has extra burst requests in for the periods near Van Allen conjunctions out through the 20th

News from MMS: 
MMS team needs to know within 24 hours if you would like them to download data. E-mail Drew Turner or Allison Jaynes if you would like them to collect data in a specific region/time for conjunction studies.

News from THEMIS: 
As an update, the THEMIS team have enabled fast survey captures at
the L-shell of BARREL and the neighboring inner magnetosphere (L> ~3)
for the context of possible conjunctions with this BARREL campaign.
Within these fast survey intervals, thye also trigger particle and wave
bursts to capture high-frequency waves (whistler-mode).

This special data collection scheme is implemented on the three inner
probes for Aug. 10-25 (starting from Aug. 11 for TH-D), based on your
estimated interval of this BARREL campaign.

News from Cluster:
No new news

News from Firebird:
We did reset the firebird spacecraft and are now taking data at a 50ms cadence continuously to cover BARREL so you can probably add that to your next update.

News from AeroCube 6:
No new news

News from EISCAT:
No new News 

News from ABOVE2:
Teams are still on standby. We will not travel to Saskatoon this weekend.

Space Weather  from ,,  and Kyoto (possibly others as well)

Swedish Institute of Space Physics: Kiruna Magnetometer:
quiet during the flight. 

Sodankylä Geophysical Observatory: Finnish Magnetometer Array:
Very quiet right before the event, but an EMIC wave around 9 - 10 UT. 

Sodankylä Geophysical Observatory: Scandinavian Riometer data
The data from the morning of the 14th is not up yet, but there is some structure in the data at the very end of Aug. 13th.  

Again, riometers are not really my thing, but it looks like there were some bursty precipitation just after midnight. 

Kiara Riometer
 the KAIRA array has been running in full-sky imaging
riometry mode (38 MHz) throughout this time period and will continue to do
so for the remainder of the campaign.

As of tomorrow (Sat 13-Aug-2016), it will additionally be running a
high-speed multi-beam, multi-frequency riometry and various other
monitoring diagnostics. This will continue for a week at least.

NOAA GOES Electron Flux:
nominal levels.

NOAA GOES Proton Flux:
nominal levels.

ACE Solar wind speed: 
Vsw =  419.4km/s

ACE Solar proton density:
density =  4.2 protons/cm^3

Sunspot number:
73  Sunspot regions 2574, 2575, and 2576 are Earthward facing but do not currently look complex enough to likely produce a CME. 

GOES Flare activity:
6-hr max B1 
24 hr max B2

kp =  1 with a 24 hour max of kp = 2

ACE SW magnetic field:
Bz = 3.0 nT North
Btotal =  4.3 nT

Coronal hole news
The next coronal hole is expected to come after Aug. 18th maybe around the 20th. We should be able to get a 10 heads up from Stereo A. Stereo A will also give us an idea about the magnetic field orientation. 

Kyoto AE:
very quiet 

Kyoto Dst:
Very quiet. But right at the time of the precipitation event it looks like there may have been a small pressure pulse that hit the magnetosphere at that time. ACE realtime data was missing during most of the flight.
