Activity on the Sun has prompted NOAA’s Space Weather Prediction Center to issue a Geomagnetic Storm Watch for Earth for March 19 through to March 21. A coronal whole is responsible for sending two coronal mass ejections (CME) towards earth. The Watch calls for a G2-level storm on a 5 point scale, with the possibility of it being upgraded to a G3-level event.
“While there is a high level of uncertainty related to the CME arrivals, there is more certainty regarding the likely CH HSS effects to begin by 21 March, with at least a G2 storm levels likely,” said the Space Weather Prediction Center (SWPC) in a statement. They added, “There is at least a slight chance for G3 (Strong) storm conditions throughout this period. Continue to follow our webpage for the latest forecasts and updates about this activity.”
