Seeing and Weather:

Observing Summary:

We started off the night in a cloud.  The clouds started clearing
around 11:30pm, but left their 100% humidity behind.  At around
2am, the humidity started dropping.  It got down to 80% at 2:45am
and I was preparing to open, but then the humidity started going 
back up (it is at 93% at 4:30am) and clouds moved in.  Since I 
have to leave early for my flight, I am going to surrender to 
the fickle weather and go to bed.

While I was waiting to see if the humidity would stop teasing me,
I took calibration frames.  During our tests on Wednesday night,
Mark Wagner noticed that it looked like something was blocking 
light at a few positions along the slit.  It's not surprising, 
but may be helpful to note that I also see this effect in my 
flats.
