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. =====ToDo===== =====Notes===== =====Weather===== 1800 - T: 47F, H: 71% 1900 - T: 43F, H: 73% 2000 - T: 43F.
