via the ARRL: Space Weather Prediction Center Says Solar Phenomena May Continue

The Space Weather Prediction Center (SWPC) said today that G4 (Severe) geomagnetic storm levels were observed at 2350 UTC on September 7 and again at 0151 UTC and 1304 UTC on September 8, due to the effects of a coronal mass ejection (CME). A G3 (Strong) or greater warning was in effect until 1500 UTC […]

via the ARRL: Solar Flares Spark Radio Blackouts, Auroral Displays Possible

NOAA’s Space Weather Prediction Center (SWPC) has issued a strong (G3) geomagnetic storm watch for September 7 through September 9. The SWPC said the watch for September 7 remains in effect due to the arrival of a coronal mass ejection (CME) and the effects of a CME on September 4. “Additionally, a G3 watch is […]

Moderate (G2) Geomagnetic Storm In Progress, G2 Warning Extended

NOAA’s Space Weather Prediction Center (SWPC) reports a moderate (G2) level geomagnetic storm is in progress. The G2 threshold was reached on March 27 at 1948 UTC. SWPC forecasters have extended the G2 Geomagnetic Storm Warning until March 28 at 0300 UTC, as coronal hole high-speed stream effects continue to influence Earth. A large, Earth-facing […]

HAARP Goes Classical During New Experimental Campaign

The just-concluded run of ionospheric investigations conducted from Alaska’s High Frequency Active Auroral Research Program (HAARP) observatory — quite likely the most powerful HF transmission facility in the world — revived the latent short-wave listener (SWL) lurking within most radio amateurs. Operating under Part 5 Experimental license WI2XFX, HAARP this month even aired some classical […]
