              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had varying high clouds all night long, with occasional radar blips.  There were some periods where NAIC was able to get decent data, but it never got a full data cube plus calibration star, so the observations may not have been useful.  We did stay open most of the night until more believable radar signals moved close about an hour before twilight, and then it was time to give up.
