ASTR 106 observation summary, 14 October 2021, DMW

In contrast to the ClearDarkSky forecast, we were never free of clouds; though observing for 4.5 hours, we only got 95 minutes of useful data. We didn't take any data until the first time the clouds began to break, providentially right before the transit started.

In all, we took 37 five-minute exposures. These were not continuous except in the ingress part of the transit light curve, and the frames at the end of the evening which comprise most of our out-of-transit baseline observations. In the official light curve, We kept frames 2-10, 16, 22-24, 27, and 33-37, rejecting all the rest because the stellar fluxes were half as large, or less, than they were at their best. 

Nevertheless, we got useful data on the transit ingress and the depth of the transit. Transit egress is less clear. If we get ingress on subsequent observations we will still be able to measure the planet's orbital period well.
