Richard observing until ~ 01:30 UT

Liam:
I opened up myself at about 01:45UT. Had problems getting the telescope to slew : a few shutdowns and startups of the tel daemon, and a power cycle of the scope cleared this error.

I thought I would try to do some more PR observing before testing morning flats. I observed M1 (Crab Nebula) from 02:00 UT. Run numbers:

I-band: r0020281-20284
R-band: r0020280, 20285-20287
V-band: r0020288-20292
B-band: r0020293-20296

Morning flats: Testing scattered light and vignetting by taking flats at different positions with detector covered...
