After strong G3 geomagnetic storm on March 6 and 7, solar wind parameters increased again around 04:00 UTC on March 11. The cause is most likely a Coronal Mass Ejection (CME) from March 6. Interplanetary magnetic field (IMF) total field (Bt) valuese steadly…
A negative polarity, coronal hole high speed stream (CH HSS) became geoeffective early March 6, 2016, causing an increase in solar wind speeds and an enhanced interplanetary magnetic field. A G1 – Minor geomagnetic storm began at 17:28 UTC, increased to G2 -…
A geomagnetic storm reaching G1 – Minor levels is currently in progress due to the arrival of the co-rotating interaction region (CIR) associated with coronal hole 55. The proton flux might reach S1 – Minor levels in the period between February 16 and 18 due to the…
'Beta-Gamma-Delta' classified Active Region 2497 produced an M1.0 solar flare at 19:26 UTC on February 14, 2016. The event started at 19:18 and ended at 19:29 UTC. After M1.0 at 10:47 UTC on February 12 and M1.8 at 15:24 UTC on February 13, this is the third…
A moderately strong solar flare measuring M1.8 at its peak time erupted from 'Beta-Gamma-Delta' classified Region 2497 at 15:24 UTC on February 13, 2016. The event started at 15:16 and ended at 15:24 UTC. There were no radio signatures that would suggest a…
An asymmetric partial-halo Coronal Mass Ejection (CME) erupted from Region 2497 late February 11, 2016. The CME was, at least in part, produced by a long duration C8.9 solar flare that peaked at 21:03 UTC. Associated with the event were Type II and Type IV radio…
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…
Prolonged effects of a partial-halo CME impact, produced by the filament eruption just of center disk late on January 14, 2016, is causing a G1 Minor geomagnetic storm on January 20, 2016. The CME reached our planet just before 21:00 UTC on January 18. Geomagnetic…
A long duration solar flare measuring M2.3 at its peak time erupted from departing Region 2473 at 00:11 UTC on January 2, 2016. The event started at 23:10 UTC on January 1 and ended at 01:01 UTC on January 2. A Type II (estimated velocity 1019 km/s) and a Type IV…
