Geomagnetic Storm Watch Cancelled by NOAA; G1 Storm Still Forecast For October 1

 

Forecasters at the Space Weather Prediction Center (SWPC) , a unit of the U.S. Department of Commerce under NOAA,which sits alongside its terrestrial National Weather Service, has canceled the Geomagnetic Storm Watch they had in effect for today and tomorrow, September 28 and September 29. However, in a separate bulletin just released, they said they expect G1 geomagnetic storm conditions on October 1 as a coronal mass ejection (CME) launched today arrives then.

 

On Thursday, a sunspot, known as AR2871, experienced two explosive eruptions, each producing a significant M-class solar flare. Solar flares are classified according to their strength, on a B-C-M-X scale. B flares are the smallest while X are the largest. Similar to the Richter scale used to help quantify earthquakes, each letter represents a ten-fold increase in energy output. Within each letter class, there is also a finer scale that usually extends from 1-9. Within the powerful X class of flares, the number could exceed 9 to reflect a massive flare event.
