Notes from the 4PM Meeting and Additional Comments.

Observers reported a delay between "enabling auto" and scripts appearing in the window (of 15 minutes). This is probably not a problem after all and was a result of their being a "break" after the standard star script.

Also discussed the fact that slit was partially obscuring the FOV at ~1am local time. Image numbers from around that time have been examined and show no obvious features, but the list has been sent to Douglas Tucker.

Unfortunately our run of good weather might be coming to an end. Clouds are forecast starting ~6am local time and look to continue through to Wednesday.
