Today, 21
February 2026, the Sun appears to be completely spotless, officially
breaking the long streak of 1345 consecutive days with visible sunspots,
a period that began after the last spotless day in June 8th2022.
I first
detected the absence of sunspots by checking the solar full-disk image on Helioviewer.org,
using the SDO/HMI white-light data timestamped 18:58:55 UTC, which
showed a fully spotless photosphere.
Immediately
after confirming this, I set up my own equipment to verify it independently.
Using a Celestron C90 Maksutov (1250 mm focal length, 90 mm aperture)
and a Canon SL3 with proper white-light filtration, I captured the
attached image showing the Sun completely devoid of sunspots.
This
observation confirms that today marks a new spotless day and the end of
the unusually long period of continuous sunspot activity during Solar Cycle 25.
You are
welcome to use the image for your daily solar activity updates.
I attach my
photo taken at 13:29 UTC in Toluca, Mexico
