              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Took a lot of tspec darks and then object.  I found at least one example of bad images at darks.0932.  The first object were also messed up but they cleared by object.1002.  There are probably other examples in the 2000 images I took tonight.
I checked the dis mask problem (not changing back to 1.5 from 5 arc sec).  I did not see the problem occur tonight after the observers finished with the 5 arc sec slit.
