BARREL Daily Update Dec. 22nd

Each day we're getting closer to our first possible launch date! Our flight readiness review is at the moment still scheduled for Dec. 23rd and if it is completed successfully we may be able to launch late Monday night! We will keep you posted as we get new information. 

The Sun is still quiet but there have been multiple M class flares. There is also a coronal hole in the Northern Hemisphere which may hit us on December 25th. Our first possibly busts collection for EFW on the Van Allen Probes will start on the 26th when they fly over the Halley and SANAE stations.

Ground Weather:

Temp.: -2 C
Wind speed: 16.5 knots 

Halley 6: 
Temp.: -5.8 C
Wind speed: 12 knots 

Payloads up: Our first possible launch date is late on the day of Dec. 23rd. 

SANAE IV: none  
Halley 6:  none. 

Payloads coming down:


Recent possible events: 


Halley Bay :

quiet with some weak EMIC and other ULF activity. 

GOES Electron Flux:

Have continued to be at normal to moderate levels and are expected to be the same for the next three days 

GOES Proton Flux:
Has stayed at background levels for the lat 24 hours and is expected to be the same over the next three days 

Space Weather from and 
Solar wind speed: 317.5 km/s 
Solar proton density: 2.6 cm^(-3)  

Sun spot number: 131  
NOAA has the likelihood of a M class flare at 40% and a 10% chance of an X class flare.  

Kp is quiet 
kp = 0 with a 24 max of kp = 1

Bz = 1.3 nT north 
Btotal = 2.8 nT  

There is a Coronal hole in the northern hemisphere which could possible hit Earth by Dec. 25th, perhaps there will be some green and red lights in the sky for Christmas :).   

From Kyoto:
AE: very quiet.  

Dst: very quiet.   

Have a good day!


  1. FIREBIRD will be ready for you. The S/C is in full science mode and we'll step up coverage once you have payloads aloft. When you post a time/day, what is it? UT, or some local time.

  2. Hi Dave, That is so exciting! We can't wait to see the conjunctions and what we can see and look at with BARREL and FIREBIRD. The dates I listed here are general but you can assume for the most part they are UT. The Antarctic stations run on UT time so the first possible launch dates would be in the afternoon/evening of December 23rd UT. When we start posting the conjunction times that we have taken, as well as the time the payloads were launched or cut down, they will be in UT.
