                ------------- ACTIVITY LOG --------------
 Observing Specialists: R.McMillan
 The sky was overcast at sunset, but the clouds thinned and we were
 able to open not too long after the end of twilight.  Occasional
 clouds continued to pose a challenge throughout the night but didn't
 prevent observations.  Seeing was moderate.
 At checkout:  air temp ~17
 Az velocity scale: 582
 Alt velocity scale: -634
 At changeover: air temp ~14
 Az velocity scale: 578
 The second half observer had some connectivity problems that seemed
 to get worse whenever he tried to use the slitviewer.  He said this
 was the second time this had happened to him (both times observing
 from on campus, once with a Mac desktop running v1.2, this time with
 a Mac laptop running v1.3).  I'm not aware of other JHU observers
 having the same problem.  He didn't have any difficulty transferring
 his spectra with ftp.
