Dear Collaborators,

Solar activity has dropped to a low-B level. NOAA 14521 produced two ~B3 flares, but it has completely rotated out of Earth's view. The target region only showed some EUV brightenings. Today, the target shall remain in the spotless region. B-class activity is expected in the next 24 hours.

The approximate position of the target on 18-Sep-2026 15:30 UT is:

N04E30 (-469", 65")

See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
