Astronomy Report – February 15th

Crew 205 Astronomy Report 15 Feb 2019

Crew Astronomer: Ghanim Alotaibi


Robotic Telescope Requested: No

Objects Viewed: No observational session was requested for tonight. I am waiting for a clear sky for the observations submitted in 13 Feb. We wanted to submit the SY MON photometry measurement to the AAVSO However, some errors were found. The CCD setting was not correct, and there are better options to select comparison stars.

As the new set up was inserted and new comparison stars were selected, the new measured value for the SY MON star was found to be 13.918. However, the magnitude value of the check star was unreasonable and was reported to observatory director.

The crew astronomer used another method to calculate the magnitude value for the target. He measured the instrumental magnitude directly from the software and performed the calculation manually. The magnitude value was found to be 14.118. The value was also reported to observatory director.

Problems Encountered: Nothing to mention
