              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Remote first half observers noted data was transfering very slow to their machines tonight (21:30 local time).  They were taking a lot of data very fast with ARCTIC in 1x1 bin mode, which was producing some large files to transfer.
No problems otherwise tonight.
