A Coronal Mass Ejection (CME) produced by the X9.3 solar flare on September 6, 2017, reached our planet at 23:04 UTC on September 7, 2017, a full day earlier than it was expected. G3 – Strong geomagnetic storming started 23:25 and increased to G4 – Severe at 23:50…
A major solar flare measuring X1.3 at its peak time erupted from Region 2673 at 14:36 UTC on September 7, 2017. The event started at 14:20, peaked at 14:36 and ended at 14:55 UTC. This is the third X-class solar flare since X2.2 at 09:10 UTC and X9.3 at 12:02 UTC on…
The eye of Category 5 Hurricane "Irma" passed over the small Caribbean islands of Antigua and Barbuda, one of the most prosperous Caribbean nations, around 06:00 UTC on September 6, 2017 with maximum sustained winds of 298 km/h (185 mph). Irma then…
A major X-class solar flare erupted from geoeffective Active Region 2673 peaking as X9.3 at 12:02 UTC on September 6, 2017. The event started at 11:53, peaked at 12:02 and ended at 12:10 UTC. This is the second X-class solar flare of the day. It comes just hours…
A powerful, long-duration solar flare measuring X2.2 at its peak time erupted from geoeffective Active Region 2673 at 09:10 UTC on September 6, 2017. The event started at 08:48 and ended at 09:59 UTC. This is the first X-class solar flare since May 5, 2015. There…
An asymmetric full halo Coronal Mass Ejection (CME) produced by the M5.5 solar flare at 20:33 UTC on September 4, 2017 is traveling toward Earth and is expected to arrive late on September 6. G3 – Strong geomagnetic storm watch is in effect for September 6 and 7….
NOAA and Air Force hurricane hunter aircraft data indicate Hurricane "Irma" has intensified into an extremely dangerous Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale with maximum winds of 280 km/h (175 mph) with higher gusts. Irma is…
Geoeffective Active Region 2673 produced 7 M-class and at least 8 C-class solar flares on September 4, 2017. The strongest was M5.5 at 20:33 UTC associated with an asymmetric full halo Coronal Mass Ejection (CME). This region has the potential to produce more strong…
An intense earthquake swarm started near Soda Springs, southeastern Idaho at 23:55 UTC on Saturday, September 2, 2017. Local authorities say they cannot ever remember any earthquake swarm in Southeast Idaho that comes even close to the current series of temblors…
A large and geoeffective Active Region 2673 (beta-gamma) unleashed a moderately strong M1.2 solar flare at 05:49 UTC on September 4, 2017. The event started at 05:36 and ended at 06:05 UTC. The region increased 10-fold in a single day, suddenly becoming one of the…
