#geomagneticstorm #solarstorm conditions are so bad this morning my bicycle Garmin couldn't locate satellite. Let's see how this morning #amateurradio #hamradio cw #morsecode #qrpradio #hb1b #pota #parksontheair activation goes.

I built a #QRPGuys 40-10 #Minituner a few years ago but never built a wire for it. Thanks to current #Geomagneticstorm conditions, I built a 40 -15 Meter Linked #EFHW that I can use with my #Youkits #YouKitsHB1B #HB1B and my #QRPlabs #QDX. #AmateurRadio #HamRadio is so much fun!

Ah, yes, the riveting saga of cosmic fireworks, where the sun flexes an M8.2 solar flare and Earth braces for a G4 geomagnetic storm, all while you wrestle with your browser settings. 🔥🌍 Who needs JavaScript when the universe is throwing a tantrum? 😂🌞

A heads up in case the sky is clear in your area tonight ( Sunday ).

#NorthernLights May Be Visible as Far South as Alabama

Streaks of colorful light could paint the #sky over a large portion of the country on Sunday night into Monday morning amid a severe geomagnetic storm.

#Aurora forecast updated!!

Space Weather Service confirms we got a class G4 storm incoming!

Aus / NZ folks: we might get some good aurora tonight — if you have clear skies, take long exposure images facing south.

Note - these are predictive models so it’s a dynamic situation.

SUBJ: ASWFC GEOMAGNETIC DISTURBANCE WARNING 25/41
ISSUED AT 2207UT/31 MAY 2025
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

A fast, halo CME was recently observed leaving the Sun headed 
for Earth. This CME is anticipated to arrive on 01-Jun at around 
2100UT +/- 12 hours. 

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL MASS EJECTION
FROM 01-03 JUNE 2025Two bar charts. The top chart shows time on the x-axis in tens of hours and on the y-axis shows the KP index. A large jump between index 2 and index 7.7 occurs from 10pm local time tonight. Bottom plot shows the ko index over next few days.Summary page of the space weather centre showing a class G4 geomagnetic storm.

Negative polarity CH HSS triggers G3 – Strong geomagnetic storm

A G3 – Strong geomagnetic storm was observed at 02:16 UTC on May 29, 2025, triggered by the arrival of a negative polarity coronal hole high-speed stream (CH HSS) at Earth. Coronal hole high-speed streams, and their associated transition zones called co-rotating interaction regions (CIRs), can create CME-like shock waves that are capable of producing strong geomagnetic disturbances and widespread auroras.

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio - HF (high frequency) radio may be intermittent.
Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. #geomagneticstorm #spaceweather #CME

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us.

😆 "India seeks internet"

A coronal mass ejection has arrived at our planet. This is the first of possibly two coronal mass ejections that were expected to arrive from filament eruptions on April 12/13. The minor G1 threshold has already been reached, the NOAA SWPC has a strong G3 geomagnetic storm watch in place for tomorrow, APR-16

Keep an eye on the data here in the hours ahead.

☝️ 😇 There is more action to come!

Not an aurora???

Many throughout the world were able to experience another great evening of auroras on New Year’s Day 2025. However, there’s a catch, some actually saw what are known as SAR arcs. These were first discovered in 1956. Researchers weren’t sure what they were and gave them the misleading name, Stable Auroral Red arcs.
