MDM Observatory 2.4m Telescope Observing Report for 2018 Oct 04

Observer(s): Rupert
Institution(s): MDM

Instrument: OSMOS/B

Worked for 10 hours (most of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity from 7:45 until 11.
   Beg: Seeing 1.4 arcsec, Clear, Winds Calm
   Mid: Seeing 1.2 arcsec, Clear, Winds Calm
   End: Seeing 1.2 arcsec, Clear, Winds Calm

Observing Summary:

Was able to open and start the night (yay!), but within
an hour the humidity rose quickly above the limit (booo).
Closed up until 11, when the humidity fell to an observable
level.

Paid closer attention to the weather widget tonight. I
monitored it on mdm24ws1 and Katie Weil monitored it on
mdm24ws2. Here's what we noticed about the MDM humidity:

1) There were occasions where the widget displayed different
humidity values at the different workstations

2) During the quick rise in humidity, the widget remained at
56%, where it was before the rapid rise, for a few minutes at
least before finally catching up

3) After the widget finally seemed to catch up with the 
conditions, on one occasion the widget at workstation
1 briefly dropped from 90% straight to 70%, then back again

Certainly worth an investigation given the widget is an 
important source of information for remote observers.
Other than that it was a great night! Better late than never.
