Although the sky appeared visually overcast 
all night, I do not think the cloud was 
very thick.  Coupled with very little aurora, 
this was enough that the SDI appeared to get 
sensible wind fields (despite weak signal).
The SDI winds should definitely be regarded 
as tentative (due to this cloud), but my
guess is that the data are fine.  SDI  
temperatures look good, and should not be greatly 
contaminated by the cloud.
A very quiet night.  Day two of the UARC campaign.
