(* means a trouble report has been issued or appended to)
Observing specialist: R. McMillan
Note: JH01 swapped some of their time with JH02 to get a more accurate
window around the eclipses.  No timeswap form was submitted for this
change because the observers for the two program had so much overlap.
There was some trouble getting Remark to run from JHU, apparently due
to the recent construction of some very solid firewalls which prevent
Remark from setting up the necessary connection.  This will be looked
into over the next few days.  For tonight, the remote observers at JHU
were fortunate enough to have an on-site collaborator who did their
observations for them.
Sometime around 23:00, the telescope pointing became distinctly
inaccurate.  Apparently, a moth had sacrificed itself on the azimuth
drive (probably one of the ~200 moths I drove out of the DIMM dome
earlier in the evening).  After 15 minutes of frantic cleaning and
pointing checks, we were able to get set up in time for the last
Jovian moon eclipse, although the tracking was somewhat poorer in this
case than the last one.
