MDM Observatory 2.4m Telescope Observing Report for 2019 Jul 28

Observer(s): Clarkson, Fiolka, Boyd
Institution(s): UM-Dearborn

Instrument: ANDOR

Worked for 6 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing .7 arcsec, Clear, Winds Moderate
   Mid: Seeing .7 arcsec, Clear, Winds Light & Variable
   End: Seeing 1 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

Clear skies for most of the night, we opened around 9:45 and 
observed until a.m. twilight at 4:45. Guiding was lost for about 
a minute, about half a dozen times, despite no particularly 
obvious clouds.

Possible problem: at the end of the night we commanded the guide 
probe to x=0 and y=0 using the xmis2 interface. After the 
commanded move, the green highlighted coords in xmis2 now show 
x=0 and y=4273, so we have doubts about whether the probe really 
returned to y=0. We can move the probe to y=4275, but not back
down to smaller y values. (If the probe indeed is not moving at 
all in the negative y-direction, we should still be able to 
guide on our science target simply by commanding the probe back 
to the x-position appropriate for our science target. So we're 
not too worried just at this time.)
