Hi Ernst

I am seeing missing segments again today on NOAA20 orbit number 15565

Are you seeing the same or is it my system just missing some files


Graham and All

I just had a look at U.K. passes of Suomi-NPP, NOAA-20, and FY-3D from the last four days.
11 passes are fine, todays NOAA-20 orbit 15565 shows the old problem again. My bet ist that
this is a software bug in the code that stitchs together the data from LANNION and SVALBARD.

NOAA-20 Orbit 15565 pass over th U.K.

Here we go again with the same problem: All segments received but one segment pretends to have the normal length of app. 85 seconds
but regarding its size compared with adjecent segments obviously is either too short in scan lines or has many black scan lines. El

I'll again report to OPS but others should do as well.
