It seems that the first satellite to go after NOAA has stopped actively maintaining the NOAA POES satellites, NOAA 18, has officially been decommissioned and is no longer active. Source
Any ideas as to what will happen now? Will there be a switch to the C-band JPSS satellites? I see that both NOAA 20 and 21 are on the database but no observations. C-band does seem a lot less accessible and common than the VHF used on the previous satellites. Will there no longer be any NOAA satellites being tracked after the 2 remaining ones are decommissioned?
