X2.9 solar flare, Welcome back 3664?

lundi, 27 mai 2024 17:22 UTC

A major X2.9 solar flare (R3-strong) took place today peaking at 07:08 UTC. The flare came from a sunspot region just behind the south-east limb. This is likely the anticipated return of old sunspot region 3664 which was the source of many major X-class solar flares during its previous visit of the earth-facing solar disk and an extreme G5 geomagnetic storm which was the first of its kind in 21 years.

Coronal mass ejection impact, New website feature!

vendredi, 17 mai 2024 17:03 UTC

A coronal mass ejection impact was detected at DSCOVR around 12:40 UTC today. The north-south direction of the interplanetary magnetic field (Bz) flipped southward to about -12nT to -12nT. A minor G1 geomagnetic storm watch is in effect for the remainder of the day.

More X-flares!

mercredi, 15 mai 2024 18:40 UTC

Sunspot region 3664 continues producing major solar flares even now that it rotated behind the west limb. An X3.4 solar flare that peaked at 08:37 UTC was highly eruptive and an impressive coronal mass ejection could be seen on LASCO coronagraph imagery from SOHO. The coronal mass ejection is however, as you might have guessed already, not aimed at our planet.

X8.7 solar flare

mardi, 14 mai 2024 19:42 UTC

What a way to sign off! Sunspot region 3664 (R3-strong) is now on the west limb and waves goodbye by producing the largest solar flare of Solar Cycle 25 which peaked at X8.7! Wow! There isn't any coronagraph imagery available from SOHO yet, but we do know the solar flare was eruptive but based on coronagraph imagery from STEREO A, the resulting coronal mass ejection is likely not aimed at Earth.

M6.6 solar flare with earth-directed CME

lundi, 13 mai 2024 18:46 UTC

Sunspot region 3664 is now close to the west limb and quieted down a bit compared to last week. Nonetheless it was the source of an eruptive long duration M6.6 solar flare (R2-moderate) that peaked at 9:44 UTC.

Small CME impact, Record visitor amount

dimanche, 12 mai 2024 10:12 UTC

Geomagnetic conditions have subsided considerably since the intense storm conditions during 10 and 11 May. Storm conditions that several times reached the Extreme G5 geomagnetic storm threshold and rivaled the 2003 Halloween Solar Storms.
