Overview

The highlights of this month were two earthquakes and a supernova in M100.
The SXV-H9 is the imaging camera, with exposures for variable stars of 120 seconds at 4x4 binning (unguided). This month's session notes are below the overview section.

Session Notes

Fri/Sat February 10/11, 2006

Despite the full moon, I imaged the supernova in M100 (5 x 60s).
SN2006X

Fri February 24, 2006

There was an earthquake tonight around 8:30. It was a moderate rumbling that I heard and felt. I actually got out of my control room chair and looked out a couple of windows because I thought someone was running heavy machinery nearby!

Sat February 25, 2006

There was a smaller earthquake this evening that I also felt while sitting in the control room. Wow, two days in a row with a quake!

Mon/Tue February 27/28, 2006

While the dark frames were running tonight, I ran an ACP script (which recorded the scope's altitude and azimuth every 2 seconds) and traced out the horizon with the telescope so I could have a reasonably accurate custom horizon in ECU.
Fortunately, the polar alignment of the scope seems is OK, so the recent earthquakes don't seem to have had any adverse affect.
