interesting, i notice meteor m2 imagery now visible for night too.. observation #15057612
dark mean hot. fire and water will show as black dot / black color. water is hotter than land at night, as it takes a lot of energy to cool water, compared less to cool land.
zoom in:
this is lake
this is sea
and this is fire hazard
Autumnal Equinox Ch 4 has been turned on
what it mean?
Meteor 2-3 or 2-4 have VIS and IR channels. Ch 1 to Ch 3 will be switched on from March to September (Only Visual Channels) during Vernal Equinox (Spring Equinox) since northern hemisphere has more day light
Ch 1, Ch 2 and Ch 4 will be on from September to March (2 VIS and 1 IR) Autumnal Equinox (Fall Equinox) giving night vision northern hemisphere has less day light
This equinox phenomenon can be seen on Geostationary satellites.
i think this MSU-MR-4 very good to detect fire. the white dots on below image are fire. correct me if im wrong. @taylorwass

Yes. Thermal IR band hence good for fires. Also sea surface temperature.
It is unfortunate that, since LRPT currently does not include analog telemetry containing calibration data, composites containing quantitative temperature data using cch4 are not available.
SatDump Log for Observation #15077437 :
[12:52:08 - 28/09/2026] (W) Analog telemetry missing from transmission. Calibration is disabled!
[12:52:44 - 28/09/2026] (D) Skipping 3.9 µm Shortwave IR (Calibrated) as it can’t be made!
