Will use 90s exp time for the rest of the session 
 +   * Percy needs to identify a clear naming convention for dark and flat frames and include in training  
 +   * Percy accidentally took another set of 30s flats under the name darks_20241222_120s, please delete that one. Thank you! 
 +   * In freezing temperatures, it may be necessary to break thermalization to close the mirror doors for flats. An alternative would be to keep the mirror doors open for darks and maintain thermalization until afterwards. 
 +   * Add mirror door malfunctions to troubleshooting training 
 +           * manually closing by hand-spinning motors 
 +           * pointing the telescope to increase gravitational torque
