Christian,

OK.

GOES-East (GOES-8 at the moment) is not scanning during the period from
4 to 7 Z. This can be seen in the GINI data in NOAAPORT:

During this time, GOES-West (GOES-10 at the moment) scans are being
used to fill in NOAAPORT GINIEAST images.
The spatial coverage of GOES-West is such that a remap into the
GOES-East GINI projection will result in no data on the eastern borders
of the image. Also, since GOES-West is being used to fill in the
images, the times of the images will reflect those of GOES-West (:00
and :30) instead of the GOES-East times (:15 and :45).
