Hopefully it will be able to resolve itself as usual.
I haven't gotten one of these broken ones yet. Sadly I already missed all NOAA-15 passes for this morning. Maybe I could try at evening.
Edit: Telemetry shows increase in AVHRR motor current:
Here is HRPT from the previous pass:
It's interesting to see how differently the onboard computer is making the APT compared to the raw data
hopefully it comes back again, last time I remember this happening it was fixed by the night pass
There was also a HIRS malfunction on NOAA 18 a while back, these NOAA sats seem quite good at fixing themselves
