Update: Terra MODIS returned to science mode on March 27, 2026 (DOY 2026-086). The blackbody reached its nominal temperature by approximately 19:23:00 Universal Time (UTC). The data have been reviewed by the calibration team and flagged as questionable/bad from DOY 2026/085 20:00:00 UTC to DOY 2026/086 19:23:00 UTC. Data after DOY 2026-086 19:23:00 UTC are safe to use.

At approximately 20:00:00 Universal Time (UTC) on March 26, 2026 (DOY 2026-085), the Terra satellite experienced an anomaly and the MODIS instrument was placed in standby mode. Although we are still receiving data and NRT processing continues, we advise users to exercise caution when using the data until it has been further verified and confirmed by the instrument teams.
