April against the rest of the year

April cloud at Anadyr averages 67% in NASA POWER's 2001 to 2020 record, close to its yearly mean of 67%. January is Anadyr's clearest month at 58%. By civil night times clear sky, April scores 2.2 hours at Anadyr, 8th of 12. Fairbanks, 1,626 km away, averages 59%, clearer by 8 points.

Civil night at Anadyr starts April at 8 h 34 min and reaches 4 h 29 min by April 30, 4.1 hours shorter. SWPC's 10 PM to 2 AM window is fully dark on every night. The sun never reaches 18 degrees down, so Anadyr gets no astronomical night in April.

April night by night

April opens toward a new moon on Apr 7, with full moon on Apr 21, in Asia/Anadyr dates. Anadyr gets 110 hours of civil night with the moon below the horizon across the month. The best of them for moon-free darkness inside 10 PM to 2 AM: Apr 1 (4 h), Apr 2 (4 h), Apr 3 (4 h).

Activity in past Aprils

Anadyr needs Kp 3 for the average oval edge to sit overhead. 500 of the 900 April days from 1996 to 2025 (56%) reached it in the GFZ Potsdam record, one of the three most active months for that level; storm days with Kp 5 or more made up 12%. Anadyr sits at 60.4 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 3.

Anadyr ranks 8th in Russia for civil night on April 15, behind Velikiy Novgorod at 7.9 hours. Coming from March (10.5 hours at Anadyr), April loses darkness, and May brings shorter nights (0.0 hours on the 15th).
