A moderately strong solar flare measuring M2.8 at its peak erupted from Active Region 2871 at 04:42 UTC on September 23, 2021. The event started at 04:35 and ended at 04:50 UTC. The flare was associated with a Type II Radio Emission at 04:44 UTC with an estimated...
September 23, 2021
A G1 - Minor geomagnetic storm watch is in effect for September 1 and a G2 - Moderate for September 2, 2021. The geomagnetic field is expected to be at quiet to unsettled conditions on August 31 due to the delayed anticipated passage of the August 26th coronal mass...
August 31, 2021
A moderately strong solar flare measuring M4.7 at its peak erupted from geoeffective Active Region 2860 at 06:15 UTC on August 28, 2021. The event started at 05:39 and ended at 06:23 UTC. The flare event follows increased solar activity with numerous c-class flares...
August 28, 2021
A glancing blow CME from the July 20 eruption could bring a chance for G1 - Minor geomagnetic storm condition on July 23, 2021. As a result, a G1 Geomagnetic Storm Watch is in effect. A ~4-degree solar filament centered at approximately N25E65 erupted from the...

New data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show that cosmic radiation levels in the Earth's atmosphere are decreasing as the new solar cycle -- Solar Cycle 25 -- gains strength. The plot below shows...
July 14, 2021
A major solar flare measuring X1.5 at its peak erupted on the Sun's NW limb -- most likely from the newly-formed Active Region 2838 -- on July 3, 2021, producing R3 - Strong radio blackout. The event started at 14:18, peaked at 14:29, and ended at 14:34 UTC....
