August 8th BARREL Daily Burst Telecon/Status Report

Hej och god morgon (Hi and good morning), 

Update Summary
Today turned out to be much nicer than the predictions, but a bit windy. Tomorrow we'll have the flight predictions for Monday, and if the ground weather is good, we'll try for a launch. 

We'll have a quick telecom tomorrow to update everyone on the launch possibilities and where the new high speed stream is relative to Earth according to ENIL.  

Let's hope for clear skies and low winds! 

News from Kiruna
Ground Weather:
Temp.:  12.8 C
Wind speed:  3.4 m/s with a max of 7.1  m/s within the last five minutes or so.  Currently Monday looks like a bit cloudy 
Precipitation (rain):  0.0 mm 

Stratospheric weather:
The winds look like they haven't yet quiet set up. They are heading west and would only give us about a 10 hour flight at maximum.  We'll find out more tomorrow.

Payloads up: First possible launch date August 10th

Payloads coming down:N/A

News from Van Allen Probes:
They are confirming when there may have been lightning and burst taken, and if they can see any lightning induced whistlers. 

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, 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 Cluster:
From Fabien -  There is sadly no conjunction possible for a possible launch on 10 August. But the first good one is on 12 August at around 11 UT. Which with 6 balloons total is a definite possibility. 

News from Firebird:
From Alex Crew - As of noon Pacific yesterday, FIREBIRD had one last set of downlinks to make tonight, after which we anticipate clearing each spacecraft's memory during Friday's passes at which point they will automatically commence taking data. In the current data-taking mode, it is expected that the memory will last for approximately ~1 month of operations. I will update after we have completed the reset.

News from AeroCube 6
From Drew - AC6 will be running in high rate mode for all of August, meaning they will have 10 Hz sampling rate.

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

Kiruna Magnetometer:
It looks like we may be at the start of a substorm here in Kiurna. The HiT&MIS cameras are taking photos, but the clouds are coming in and out of view. Fingers crossed we saw something. Along with this possible substorm it looks like we have some ULF wave activity .

Finish Magnetometer Array:
Yesterday there was some strong ULF wave power, but no clear EMIC Waves. 

GOES Electron Flux:
GOES 2 MeV electrons appear to be returning to nominal values. However there is still a lot of structure associated with them.

GOES Proton Flux:
GOES proton fluxes are remaining nominal.

Solar wind speed: 
Vsw = 479.0 km/s

Solar proton density:
density = 4.9 protons/cm^3

Sun spot number:
95 - but there is one very big one (number 2396)

Flare activity:
Sunspot AR2396 is now in a beta-gamma configuration. For classification of sunspots see and We currently have a 55% chance of an M-class flare. 

kp =  2 with a 24 hour max of kp = 5

SW magnetic field:
Bz = 0.0 nT 
Btotal =  10.2 nT 

Coronal hole news
There are no large coronal holes currently on the Earthward facing side of the Sun. 

A slight increase in AE, perhaps a small substorm. 

Dst is currently very quiet. 

Daily BARREL check in information: NO TELECON TODAY
Time: 7pm Kiruna time (13:00 Dartmouth time, 12:00 Minneapolis/Iowa time, 11:00 University of Colorado Boulder, 10:00 Berkley time). 

Phone number +1 641-715-3580
Access code 481960

Swedish Phrase of the day:
From Par - our safety guy at ESRANGE
Hopa Vindstilla - Hope for no wind! A very good hope we have for Monday morning. 

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

Alexa and the BARREL team.
