There were clouds passing by during the second set of scans (scans 11 to 20,
which were 01/18/2020,17:11:26 to 01/18/2020,17:15:04), so we had to stop a few
times to wait for the clouds to pass and continue scanning. It is possible that
some of the scans still had a bit of cloud between the instrument and the sun.
