 +0333 - Found 9 gem and Beta Tau but because of uncertainty around the correct exposure time to use, elected to just wait 20 minutes between consecutive captures of GB6 J0742+5444. We reach ~25,000 counts at 6s, but that is a considerably larger exp time than what we have been using for the calibrators thus far.

 +0530 - capture paused, sky cover shot up considerably. Thick cirrus clouds making it difficult to view the target. Will wait an hour to see if it will clear up - otherwise we will begin shut down procedures. Photos of the sky cover can be found in the discord thread for this night. The paused captures were left in the folder C:\Users\Administrator\Desktop\DDC Captures\2025-12-03_ZWO-ASI533MM-Pro_PICSI2\2025-12-04_ZWO-ASI533MM-Pro_PICSI2\GB6-J0742+5444\05_48_31

 +0630 - sky cover continues to be obstructive, doing sky flats and beginning shut down

 - Having trouble identifying targets using the GAIA script, received error messaged about the new folder that is created to hold the region files. Ian Kirn logged onto the NUC and resolved the error, but it is not clear what the reliable fix for this is. The error occurred multiple more times later in the night. The star field in question was confirmed to contain the target star, so further use of the gaia script will not be necessary for the remainder of the night.  - Having trouble identifying targets using the GAIA script, received error messaged about the new folder that is created to hold the region files.

-- The 0201ET captures of GB6J0742+5444 contain a naming error. The midnight shift operators forgot to erase the "region" designation used for the GAIA script before beginning the official captures of the target. There are too many capture files to change manually+- The 0201ET captures of GB6J0742+5444 contain a naming error. Ian probably forgot to erase the "region" designation used for the GAIA script before beginning the official captures of the target.

 +- SIMBAD lists GB6J0742+5444 and Bl Lac to be the same object but this is untrue. The equatorial coordinates do not match up
