              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Bad weather kept us closed all night. Called it at 04:30. Took series of
Tspec images during downtime. Images in /tspec_tests/dark.0###.fits.
First bad image at 0350.fits. It did not correct itself over the next 650
images. Although, the contrast, or counts, of each image changes slighly.
I did not view every image to verify the pattern, but note the difference
between dark.0750.fits and dark.0800.fits, for example.
The object images, beginning at 1006.fits, were no different. Got nothing
but corrupted images until the end of the night.
