A C3.8 solar flare erupted from Active Region 2816 at 04:35 UTC on April 22, 2021, producing a coronal mass ejection (CME). The event started at 04:10 and ended at 05:00 UTC. The location of the source region favors Earth-directed CMEs. The flare was associated with…
A moderately strong solar flare measuring M1.1 at its peak erupted at 23:42 UTC on April 19, 2021. The event started at 23:19 and ended at 23:59 UTC. The source was Active Region 2816 (beta). Associated with this event were Type II (shock velocity of 750 km/s) and…
Solar wind parameters over the past 12 hours indicated the arrival of a slow-moving Coronal Mass Ejection (CME), likely produced on April 10. A period of G1 – Minor storming began at 08:59 UTC on April 15. Another enhancement in parameters is expected on April 16…
Earth is under the influence of negative polarity coronal hole high speed stream (CH HSS) over the past 24 hours, sparking G2 geomagnetic storming. The source is a polar connected coronal hole located in the Sun's southern hemisphere. Geomagnetic K-index of 5…
Earth is under the influence of a negative polarity coronal hole high speed stream, sparking G1 – Minor geomagnetic storm and auroras as low as Michigan and Wisconsin, U.S. Enhanced solar wind parameters were observed on March 13, 2021, due to co-rotating…
Earth is under the influence of a negative polarity coronal hole high speed stream (CH HSS) on March 1, 2021, sparking G1 – Minor and G2 – Moderate geomagnetic storming. Solar wind speed started increasing late February 28, from 369 km/s at 22:00 UTC to 521 km/s at…
Solar wind parameters in 24 hours ending 12:30 UTC today were indicative of a slightly enhanced and disturbed interplanetary magnetic field (IMF) due to weak coronal hole high speed stream (CH HSS) influences. Total IMF strength was variable, but steadily increased…
An intensification trend of cosmic rays activity reported last month by SpaceWeather.com continues. The latest balloon flight over California on February 5 observed the highest value yet. The gathered data shows that cosmic rays in the mid-latitude stratosphere are…
An increased activity of cosmic rays has been observed around the Arctic Circle by the neutron monitors during the last year. The same trend was also noted in an independent measurement project carried out by the Spaceweather.com and the students of Earth to Sky…
