BARREL Daily update Jan 11th

Hi all, 

Halley had another successful launch! 2M is up on the soc and looking good. SANAE is also hoping to have a launch. Reiner sent along a photo.  2W is looking like it will be cut downy the end of the day. It has been dropping in altitude and the x-ray data is no longer of science quality. Of course once it's on the ground we'll have another magnetometer perhaps in line with the AGO chain which could be useful. 

It looks like 2T might make it all the way back to Halley before having to be cut down. I wonder if it will fly close enough that they could either recovery it or see it through a camera/telescope! Its our first BARREL payload to circumnavigate the globe... even if it was only at the pole. 

Ground Weather:
Temp.: -8. C
Wind speed: 23 knots but coming down in the afternoon to between 3 - 6. 

Halley 6: 
Temp.: -2.3 C
Wind speed: 10 knots 

Payloads up: Possible launch today from either site
Halley 6:  2T, 2I, 2K, 2L, 2M

Payloads coming down:
2W (likely later today)

Halley Bay Search Coil Magnetometer :
Very quiet.  

GOES Electron Flux:
The electron levels have gone back down to moderate and are staying there. 

GOES Proton Flux:
They are recovering and starting to dip down below the SEP cutoff 

Space Weather from and 
Solar wind speed: 382.4 km/s 
Solar proton density: 2.3 cm^(-3)  

Sun spot number: 138
NOAA has the likelihood of a M class flare at 75% and a 35% chance of an X class flare.  

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

Bz = 2.6 north
Btotal = 5.5 nT  

There is a coronal hole which should hit earth on or around 12 - 13 of January. Some are hypothesizing that this coronal hole is to blame for the underwhelming CME. It has been floated that perhaps the winds from the coronal hole pushed it further East so we only saw the edge of it. 

From Kyoto:
AE: very quiet but only a few magnetometers reporting.  

Dst: quiet.
