                ------------- ACTIVITY LOG --------------
1st half Observing Specialist: G.Saurage
Snowing (lightly) at 17:19.
Truss lamps gui was empty: tlamps status did not fix it (until after all
the DIS issues).
DIS problem: Dale was taking biases, 2nd one failed (error message in
TUI), and then DIS was pretty much not responsive. DIS init gave an error
about incorrect arguments. I restarted MC and tried homing everything. DIS
exposure status reported that an exposure was still in process but the
shutter was closed. Then I tried aborting the exposure but got only
errors. I thought communications were down so I restarted the hub
connection to DIS, but still nothing. Eventually we called Fritz and he
did a DIS stop and start and that seemed to fix things. He also was able
to clear the truss lamps.
The same problem happened again latter. While trying to take some
HeNeArs. The exposure window reported exp failed and clicking start again
only would begin the integration countdown but never read out. I did what
Fritz did earlier to try to clear things.
in disicc: dis stop, dis start
in tcc: restart hub, home shutter, and dis init
Things seemed to come back but again the truss lamps were not working -
tlamps status was timing out, then suddenly it cleared.
It happened again (3rd time) after turning on the lamps again and dis home
shutter cleared it. Lamps were messed up again.
DIS slitviewer problems: Slitviewer shutter was VERY sticky tonight. Every
other frame was blank or partially open. This renders the focus scripts
inoperable and is just plain annoying. Exercising the shutter did not seem
to help for quite a while. Eventually longer exp.( 1u per 0.1 cubic feet.
