[1000 km/sec - < 500 MeV - > 50nT] These three values reflect the intensity of the #geomagnetic storm that hit the #Earth at the beginning of the week. Caused by an X1.9-class solar flare, it produced magnificent auroras—even at mid-latitudes.

Thanks to the vast network of instruments aboard space telescopes (SOHO, Solar Orbiter, etc.) and distributed on the ground, astronomers were able to track the evolution of this solar storm and its propagation toward Earth: https://www.irap.omp.eu/en/2026/01/all-about-the-solar-flare-of-january-18-2026/

There are some vertical photos for you. Aurora tonight.

MAHOOSIVE #geomagnetic #SolarStorm going on - stronger than last night. And here at 51 degs north its windy and wet. Bugger.

Last night there was a very annoying high haze which meant i got a vague purpleish sky to the north at best.

Damn

Higher levels of #CarbonDioxide will make the upper atmosphere less dense overall — but more prone to dramatic increases 📈 in density during #SolarStorms, which could have significant implications for technology like #GPS, #satellite 🛰️ internet and the #ISS. The May 2024 #geomagnetic superstorm caused nearly half of all satellites in #LEO to automatically fire their thrusters to stay spaceborne https://www.astronomy.com/science/satellites-face-new-challenges-from-solar-storms

А далей была найбольш актыўная фаза ззяння. Я ня ведаў, якую фотку выбраць, таму глядзіце ўсе. Цяжка было спыніцца здымаць. Амаль усе здымкі па 8 сек экспазіцыі, апошні - 30 сек. Усё адбывалася на працягу прыблізна 40 хвілін. 13 снежня 2025.

And then there was the most active phase of Aurora (about 40 minutes). I didn't know which photo to choose, so look at all of them. It was hard to stop shooting. 13 December 2025.

#SpaceWeather effects affect our technological systems. The currents a #geomagnetic storm induces in power lines can destroy transformers. For long-distance power lines aligned parallel to the geoelectric fields, the induced voltage can be thousands of volts. Many of today’s #electrical systems are built around #computer chips that are not robust to high-voltage surges. The hardest-hit regions could be without #power for days or weeks until equipment could be delivered https://spectrum.ieee.org/us-regions-most-vulnerable-solar-storms

G2 geomagnetic storm and aurora forecast for December 3-4 following CME from X1.9 solar flare

NOAA’s Space Weather Prediction Center (SWPC) issued a G2 – Moderate geomagnetic storm watch for December 3 and 4, 2025, following a coronal mass ejection (CME) associated with the X1.9 solar flare from Active Region 4299 on December 1. The CME is expected to deliver a glancing blow to Earth’s magnetic field, coinciding with a co-rotating interaction region (CIR) and a sector boundary crossing, increasing the potential for moderate geomagnetic storming and visible auroras at mid-latitudes. #spaceweather #CME #solarflare #aurora #geomagnetic storm

A #Geomagnetic #Storm is a major, temporary disturbance of Earth's magnetosphere caused by a potent injection of solar wind energy, typically from a Coronal Mass Ejection (CME), which significantly alters the planet's magnetic field.

These storms can trigger dazzling auroras at lower latitudes but can also cause damaging geomagnetically induced currents (GICs) that disrupt power grids, degrade GPS signals, and increase drag on low-Earth orbit satellites.
