Impulsive X1.5 solar flare erupts from geoeffective AR 3006
An impulsive solar flare measuring X1.5 erupted at 13:55 UTC on May 10, 2022, from Active Region 3006. The event started at 13:50 UTC and ended at 13:59.
Highlights of solar and geomagnetic activity: May 2 – 8, 2022
olar activity ranged from low to high levels from May 2 to 8, 2022. In total, the Sun produced 79 C-class solar flares, 8 M-class and 1 X-class. Over the past 30 days, 35 M-class flares were produced and 4 X-class.
Moderately strong M5.7 solar flare erupts from Region 3004
A moderately strong solar flare measuring M5.7 erupted from geoeffective Active Region 3004 at 08:59 UTC on May 4, 2022. The event started at 08:45 and ended at 09:10 UTC.
X1.1 solar flare erupts from the Sun’s SE limb
A major solar flare measuring X1.1 erupted from a region located at the Sun’s southeastern limb at 13:25 UTC on May 3, 2022. The event started at 13:09 UTC and ended at 13:31.
Major X1.1 solar flare erupts from the Sun’s west limb
A major solar flare measuring X1.1 erupted from the Sun’s west limb at 13:47 UTC on April 30, 2022. The event started at 13:37 UTC and ended at 13:52.
M9.6 solar flare erupts from Region 2993, CME produced
A strong solar flare measuring M9.6 at its peak erupted from Active Region 2993 at 01:59 UTC on April 21, 2022. The event started at 01:47 UTC and ended at 02:05. A coronal mass ejection (CME) was produced and there is a possibility there is an Earth-directed component. Region 2993 is one of two moderately…
Major X2.2 solar flare erupts just beyond the southwest limb of the Sun
A major solar flare measuring X2.2 at its peak erupted at 03:57 UTC on April 20, 2022 from a region located just beyond the southwest limb of the Sun – likely former Region 2992. The event started at 03:41 UTC and ended at 04:04.
Major X1.1 solar flare erupts from Active Region 2994
A major solar flare measuring X1.1 at its peak erupted from newly numbered Active Region 2994 at 03:34 UTC on April 17, 2022. The event started at 03:17 UTC and ended at 03:51. A coronal mass ejection (CME) was produced during the event but the location of the source region does not favor Earth-directed CMEs. This will change in the days ahead as the region turns into geoeffective position.
CME hits Earth, sparking G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by a large filament eruption at 05:21 UTC on April 11, 2022 reached Earth around midnight UTC on April 14, sparking G2 – Moderate geomagnetic storm.
Filament eruption produces Earth-directed CME, G2 – Moderate geomagnetic storm watch in effect
A large filament eruption took place around Active Region 2987 – located at a geoeffective position – producing a C1 solar flare at 05:21 UTC on April 11, 2022. The event produced a full halo CME and WSA-Enlil model indicates arrival at Earth early on April 14. As a result, a G2 – Moderate geomagnetic…
