Space Weather

Do you understand space weather? There are many myths and a lot of hyperbole out there which confuses peoples' conceptions and expectations.

I've just published a brief space weather course giving the facts in a concise and informative way. It should help you to understand the terms used and the processes involved in the creation of space weather.

Solar flare alert: An M4.4 flare peaked at 23h52 UT 18 Apr. A type II radio emission was observed.

This was the first significant flare in five days, and it originated from a new active region emerging on the east limb.

Space Weather Message Code: ALTK08
Serial Number: 50
Issue Time: 2025 Apr 16 2054 UTC

ALERT: Geomagnetic K-index of 8, 9-
Threshold Reached: 2025 Apr 16 2055 UTC
Synoptic Period: 1800-2100 UTC

Active Warning: Yes
NOAA Scale: G4 - Severe

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

- Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude.

- Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify.

- Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur.

- Navigation - Satellite navigation (GPS) degraded or inoperable for hours.

- Radio - HF (high frequency) radio propagation sporadic or blacked out.

- Aurora - Aurora may be seen as low as Alabama and northern California. #spaceweather

A space weather inspired pub sign :-)
I check the swpc.noaa website quite often as I like to see what the sun's 'face' looks like, what the auras are up to and I find the solar wind prediction model incredibly soothing... A bit like the BBC shipping forecast.

This is (faux) gold leaf and gold enamel paint. Commissions taken - get in touch if you want it, or something similar.

Space Weather

A large coronal hole is facing Earth, sending a fast stream of solar wind towards us.

But DON'T PANIC! It should be mostly harmless.

The magnetic polarity of the wind from this hole matches Earth's, so at most is likely just to cause a little "buffeting" to our magnetosphere, rather than produce huge spectacular auroral lights down to the equator or knock out electricity grids.

View from my driveway tonight. With these auroral bands, you have a maximum level of energy that is stored in the earths magnetic field. When these maximum levels are reached, it creates a breakup, or otherwise known as a corona. Where the magnetic bands swirl and break apart, releasing the concentrated energy into a more broad, mist like auroral haze.
But for those few minutes of eye watering wonder, it’s quite a good time.
