               ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Coughlin
 Clear skies all night, photometric most of the time. Seeing was
 fairly variable, bouncing between 0.8" to 1.6" in infrared. No
 telescope problems. Only instrument problem was an observer wanted to
 stop a tspec exposure halfway through and read out the existing data,
 but there was no option to do so, and thus he had to abort and lose the
 exisiting data. I edited existing PR 879 to see if a "Stop" button could
 be added to Tspec similar to what NICFPS has so the user can stop an
 exposure and read out the existing data.
