Small cloud passed by the sun between scans 5 and 6 while changing between
operators. It is possible that scan 6 still had a thin bit of cloud between the

of some sort in the atmosphere, which was easiest to notice when looking away
from the sun; though it could be I am just not accustomed to what the
atmosphere is supposed to look like in the region.
