Surprisingly strong geomagnetic storm

Knowing that a solar wind stream was heading for Earth, forecasters predicted a geomagnetic storm last night. However, they didn’t predict it would be so strong, a G3-class event

Hurricane Watch Net Currently Not Active but Still Eyeing José

The Hurricane Watch Net (HWN) suspended operations for Hurricanes Irma, José, and Katia on September 11 at 2100 UTC, after being continuously active for more than 6 days, said HWN Manager Bobby Graves, KB5HAV. Now, Hurricane José, a Category 1 storm, is the sole storm in the HWN’s sights.

“We remain at Alert Level 2 — Monitoring Mode,” Graves said. “People along the US East Coast should closely monitor this storm, as they could possibly be affected early next week.”

Moderate Geomagnetic Storm Watch Issued

The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) has issued a moderate (G2) geomagnetic storm watch for September 13. A coronal hole high-speed stream, originating from a recurrent, positive polarity coronal hole on the Sun’s surface, prompted the prediction. Minor (G1) geomagnetic storming is possible on September 14.

 

It’s been a turbulent time on the…

Caribbean Emergency and Weather Net Requests Clear Frequencies

With the passage of Hurricane Irma, radio amateurs in the Eastern Caribbean have been extremely busy passing information into and out of the affected area, Eric Mackie, 9Z4CP, told ARRL.

“The Caribbean Emergency and Weather Net (CEWN) has been facilitating this exercise,” Mackie said. “We have however, been experiencing QRM from stateside stations from time to time.”

Mackie said the CEWN is askin…

RED ALERT – Aurora Now!

The current disturbance level is at 309.7nT. Pity we have clouds in Birmingham (UK) but they have quite a nice pink tinge to them.
