BARREL Daily update Aug. 11th 2016

Update Summary

KML files for MMS1 are up on the google earth dropbox folder. Hopefully later today we'll have THEMIS and LOMONSOV up as well. 

Currently it is looking less likely to have a large CME from the current active regions, but things can always change. 

News from Kiruna

Next possible launch date - Saturday evening of Aug. 13th for the early Sunday morning conjunction on Aug. 14th

Payloads coming/which came down:
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 the
estimated interval of this BARREL campaign.

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

Swedish Institute of Space Physics: Kiruna Magnetometer:
quiet but it looks like this past evening there was a substorm. 

Sodankylä Geophysical Observatory: Finnish Magnetometer Array:
Some broad band activity on  Aug. 10th. 

Sodankylä Geophysical Observatory: Scandinavian Riometer data
Just a reminder Riometers are not my area of expertise, but it does look like there may have been precipitation from around Aug. 10th around noon and during the period of the potential substorm. 

NOAA GOES Electron Flux:
We can see the end of the activity from yesterday's event and currently the levels look nominal. 

NOAA GOES Proton Flux:
nominal levels.

ACE Solar wind speed: 
Vsw =  566.4 km/s

ACE Solar proton density:
density =  0.7 protons/cm^3

Sunspot number:
69  and Sunspot AR2571 is rotating off the disk. Sunspot regions 2574, 2575, and 2576 are still rotating around but do not currently look complex enough to likely produce a CME. 

GOES Flare activity:
6-hr max B5 
24 hr max B5

kp =   2 with a 24 hour max of kp = 3

ACE SW magnetic field:
Bz = 1.9 nT South
Btotal =  5.0 nT

Coronal hole news
The high speed stream has reached the Earth and the solar wind velocity is expected to stay high until about August 12th according to the WSA-ENLIL models. However we can already see that the velocity is dropping. 

Kyoto AE:
Although the Kiruna magnetometer looked like there was a large period of activity, the realtime AE from Kyoto is very quiet.  

Kyoto Dst:
Very quiet. 

De vanligaste paprikorna är gröna, röda och gula. 
The most common bell peppers are green, red, or yellow. 

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

Alexa and the BARREL team.
