              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
TSPEC checkout images looked fine but by 21:20 I got corrupted images again.  I waited about 30 mins and the images looked fine again.  2 hours later the images were bad again (although they looked a bit different, see images tspec_dark.0027 & 28.
We used TSPEC 2nd half with no problems.
