BARREL Daily update Aug. 15th 2016

Update Summary
We had a successful launch and will hopefully have a second this coming Tuesday. NOAA expects that there may be a small High Speed Stream (HSS) with velocities toping out at about 400 Km/s hitting Earth around the 16th. There may be another HSS coming around Aug. 20th. These HSS may lead to either geomagnetic storms or substorms. Both storms and substorms can cause the electrons from the radiation belts to be lost to the atmosphere. 

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 Instrument
EMFISIS has extra burst requests in for the periods near Van Allen conjunctions out through the 20th. Chorus waves were observed by both spacecraft (better conjunction with RSBPA) during the precipitation event observed by BARREL. 
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:
AC6 was operating and had a pass over Kiruna after our balloon was terminated. However, they also observed some structure in the observed electrons. 

News from EISCAT:
No new News 

News from ABOVE2:
We will try for a Tuesday evening launch (Aug 16) in order to have the balloon in the air on Aug 17th UTC . Surface weather looks good, there is a good conjunction with RBSP, and a recurrent coronal hole is likely to be geoeffective. NOAA is calling for a G1 (minor) storm on the 16th, although the exact timing is very uncertain. Teams in Calgary/Seattle/Edmonton are asked to travel to Saskatoon on Monday.

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

Swedish Institute of Space Physics: Kiruna Magnetometer:
quiet during the flight, but then saw two EMIC waves, one from 12 - 14 UT and another from 16 - 18 UT on Aug. 14th after the event had occurred. 

Sodankylä Geophysical Observatory: Finnish Magnetometer Array:
It looks like there was an EMIC wave between 12 - 15 UT at all stations on Aug. 14th. Kilpisjarvi showed an increase in broad band ULF frequency ranges and then a EMIC wave which started at about 5:00UT. 

Sodankylä Geophysical Observatory: Scandinavian Riometer data
The data from the 14th looks like there was little precipitation until after 02:00 UT and then it died down after about 03:00UT at the higher latitude riometers. There was structure throughout the rest of the day at all sites as well.  

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, but looks to be on the rise. 

NOAA GOES Proton Flux:
nominal levels.

ACE Solar wind speed: 
Vsw =  306.4km/s

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

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

GOES Flare activity:
no flares during the Aug. 13-14 launch
6-hr max B2 
24 hr max C3 

kp =  1 with a 24 hour max of kp = 2

ACE SW magnetic field:
Bz = 3.8 nT North
Btotal =  5.7 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.

Jag frågade illustratören att rita en bild åt mig. 
I asked the illustrator to draw me a picture. 

Hej då och god kväll från Kiruna (Good bye and good evening from Kiruna), 

Alexa and the BARREL team.
