Log
1700 - Started start up procedures and swapping PISCARR for PICSI2
1755 - Started taking darks
1838 - Started taking dome flats
1859 - Adjusted focus to 2623.8
1900 - Slewed to AM Herc
1905 - Starting taking captures of AM Herc
2121 - Started taking captures of Mkn 590
2245 - Slewed to Alpha Lac
2250 - Began captures of Alpha Lac
2258 - Slewed to Phi Cas
2300 - Began captures of Phi Cas
2315 - Having issues with finding 3C 138; used the Python script to attempt identification, but still cannot find the target. Used Stellarium and Simbad coordinates to locate the star, to no avail
2345 - Pinged Ian for assistance, he notices that the images might be inverted.
0025 - Ian takes over the NUC controls and confirms that we are on the desired target.
0027 - Slewing to 3C 138
0030 - Begin captures of 3C 138
0155 - Slewed to Phi Cas
0200 - Begin captures of Phi Cas
0210 - Slewing to 3C 138
0215 - Begin captures of 3C 138
0243 - Alpha Lac is now at 6deg altitude, skipping and taking off observation cycle
0344 - Slewing to Phi Cas
0346 - Begin captures of Phi Cas
0355 - Slewing to Phi Cas
0400 - Begin captures of Phi Cas
0522 - Targets will be too low, slewing to Beta Tau for calibration
0526 - Begin captures of Beta Tau
0536 - Our main science target 3C 138 is currently at 28deg altitude. If we start a 90 min capture, the telescope will move far beyond the horizon limit. Because of this, Percy made the executive decision to end the night a bit early.
0545 - Shutdown procedures completed, all 20241124 files have been moved to 20241123.
