[9/7/17] While Texas is still suffering from the devastating effects of Hurricane Harvey, and the Caribbean Islands seeing major damage from Hurricane Irma, with the U.S. east coast preparing for landfall, and on the other side of the country massive wildfires raging out of control, we now note that Earth is under a geomagnetic storm watch for September 6-7, 2017.
Via NOAA, Space Weather Prediction Center: “The geomagnetic storm watch for the 6 and 7 September, 2017 UTC-days has been upgraded to G3 (Strong). The G3 Watch is in anticipation of the expected arrival of a coronal mass ejection (CME) that took place in association with an M5 flare (R2-Moderate radio blackout) observed on 4 September at 2033 UTC (1633 ET). Current analysis and forecasts reflect CME arrival late on 6 September, 2017; with CME effects continuing into 7 September. Keep checking our SWPC website for updates to the forecast.”
NOTE – While this event holds nearly zero chance of causing anything as disastrous as the 1859 solar storm called the Carrington Event, a G3 geomagnetic storm does fall right in the middle of the their 5 point rating system and is listed as a “strong” event, as shown in the chart below:
