Strong G3 geomagnetic storm watch for 23 March

sábado, 22 março 2025 17:58 UTC

Yesterday around 16 UTC an M1.2 solar flare took place around sunspot region 4028. The solar flare triggered a filament eruption which erupted from the center of the earth-facing solar disk.

Coronal hole faces Earth

quarta-feira, 5 março 2025 21:47 UTC

A coronal hole is facing our planet today which is sending a high speed solar wind stream towards us which could cause enhanced geomagnetic conditions (and thus aurora!) in the days ahead.

X2.0 solar flare from sunspot region 4001

domingo, 23 fevereiro 2025 19:55 UTC

It has been 53 long days but we have finaly seen another X-class solar flare coming from the Sun today. Sunspot region 3947 produced an X1.8 solar flare on 4th of January and since that day... silence... but today departing sunspot region 4001 produced an X2.0 solar flare.

Coronal hole faces Earth, Minor G1 geomagnetic storm watch

sexta-feira, 7 fevereiro 2025 19:26 UTC

Geomagnetic conditions have been relativity quiet lately with no strong geomagnetic storms to speak of. Coronal holes are however making a return and we are seeing them more regularly appearing and influencing the weather in space around Earth and thus the aurora dancing above our heads.

Sunspot region 3947, X-class solar flares

sábado, 4 janeiro 2025 17:46 UTC

Solar activity has been on the rise again thanks to flaring activity coming from sunspot region 3947. It has been responsible for multiple M-class events and three low-level X-class events including an X1.8 solar flare today that peaked at 12:48 UTC.

Two earth-directed coronal mass ejections

segunda-feira, 30 dezembro 2024 19:31 UTC

Our Sun remains fairly active today but no coronal mass ejections were launched today with a clear earth-directed component. We do however want to talk about yesterday's events again as more data and opinions have emerged...

Strong G3 geoamagnetic storm watch issued

domingo, 29 dezembro 2024 23:09 UTC

It has been quite an eventful day on the Sun with 18 M-class solar flares and even an X1 solar flare. Sunspot region 3936 produced most of these events including the X-flare but also sunspot region 3938, 3939 and 3940 were contributors.

M9.0 solar flare with earth-directed CME

segunda-feira, 23 dezembro 2024 17:53 UTC

Sunspot region 3932 produced an M9.0 (R2-moderate) solar flare today which peaked at 11:12 UTC. The solar flare was fairly impulsive but it was associated with a Type II radio emission indicating the possible launch of a coronal mass ejection something which we can confirm now thanks to SOHO/LASCO coronagraph imagery.
