August 20th Daily e-mail.

Hej och god morgon (Hi and good morning), 

Update Summary
Kathryn rescued payload 3D today while the rest of us got ready for tomorrows launch. 

According to ENLIL it looks like starting late tonight we'll start seeing some higher velocity solar wind speeds. The peaks seem to be at right about midnight, early morning on the 20th and then another on the 23rd. It looks like there may be an even larger (broader?) and faster high speed stream coming shortly after the 25th. Definitely something to look forward to. 

As requested yesterday, here is the link to our CDF files for all campaigns.

News from Kiruna
Ground Weather:
Temp.:  24.5 C
Wind speed:  1.4 m/s with a max of 2.7 m/s within the last five minutes or so.  

Stratospheric weather:
Turnaround may be here but the winds are still fast and unpredictable. 

Payloads up: Next possible launch Friday morning 9am. 

Payloads coming/which came down:3A launched at ~ 13:50 UT on August 10th and terminated at about 20:30 UT on August 10th
3B launched at ~4:30 UT on August 13th and terminated at about 17:18 UT on August 13th. 
3C launched at ~12:10 UT on August 17th and terminated at about 03:33 UT on August 18th. 
3D launched at ~6:02 UT on August 19th and terminated at about 12:50 UT on August 19th. 

News from Van Allen Probes:
Some new times for collection added. EMFISIS saw a lot of activity on the 17th. 

News from MMS: 
No new news.

News from THEMIS: 
No new News

News from Cluster:
From Fabien -  Just a comment about Cluster : A conjunction is possible on 20 and 21 (not so close on 20), but there are no conjunction possible with Cluster before 20-21 August

News from Firebird:
No new news

News from AeroCube 6
From Drew and Bern - They had some great conjunctions and are now trying to get down the data. 

News from EISCAT
No new News 

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

Kiruna Magnetometer:
It looks like there it is starting to get active (Yay as we finally have "night" and could potentially see the aurora.). It looks like there's an EMIC wave between 9-10 UT and another starting at about 12 and possibly have ended but the graph ends so it's hard to tell. 
It looks like there was some EMIC wave activity yesterday both in the morning before 3UT and again at about 22 UT but not while we were flying. 

It looks like there was some nice precipitation throughout the day at IVA, SOD, and OUL all seem to have observed at least some precipitation in the morning. 

GOES Electron Flux:
Both >2MeV and >800 keV appear to be enhanced and climbing at the moment. 

GOES Proton Flux:
GOES proton fluxes are remaining nominal.

Solar wind speed: 
Vsw = 455.3 km/s

Solar proton density:
density = 2.3 protons/cm^3

Sun spot number:
36.  only one numbered sunspot.  

Flare activity:
Very quiet... 

kp =  2 with a 24 hour max of kp = 3

SW magnetic field:
Bz = 7.6 nT South
Btotal =  4.9 nT 

Coronal hole news
There is now an Earthward facing coronal hole. It is more poleward, but much larger than the last. There is a second coral hole which is a bit smaller but at the solar equator which is starting to possibly become Earth directed. The current Earthward facing coronal hole is expected to hit around the 21st or 22nd. 

It looks like we may have just had a nice substorm activity  

With Dst having reach > -10 nT I think we can say that the last storm or two has recovered. 

Swedish Phrase of the day:
A street names down the road
här bor jag  = Here I live

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