Geomagnetic Impulse from X1.5 Class Flare

Post by Carbon60 »

I wasn't lucky enough to see/image the flare myself (unlike Nigella...congratulations on that :) ) but my magnetometer (which runs 24/7) did indeed capture something of the event in terms of a geomagnetic impulse.

A powerful flare such as this ionise Earth's atmosphere, create powerful currents at high altitude, which in turn alter our local magnetic field.

Here's an explanation from SpaceWeather.com:

"The phenomenon is called a 'magnetic crochet.' Radiation from the flare ionized the top of Earth's atmosphere and caused currents to flow 60 km to 100 km above Earth's surface. These currents, in turn, altered Earth's polar magnetic field. Unlike geomagnetic disturbances that arrive with CMEs days after a flare, a magnetic crochet occurs while the flare is in progress. They tend to occur during fast impulsive flares like this one".

Here are my data through the entire day with the pulse circled in red.

I haven't seen this type of event before. Hopefully more to come in the coming years as cycle 25 develops.

Thanks for looking.

Stu.

Thank you Stu for your continued monitoring and the capture from AR2838.

Cheers

Wow!! I'm really impressed Stuart :bow :bow :bow

The Spaceweather app was really freaking Darren out yesterday as it was sending multiple alerts during the X-Class event like 'X-ray bombardment of Earth detected' and it was scaring him :) Glad to see you picked up the bombardment in another format.

Ha...ha... I can just imagine ;) I hope he’s reassured that we’re not heading towards Armageddon lol.
