Geomagnetic Storm Watch Issued by NOAA for Early This Week

The National Oceanic and Atmospheric Administration’s Storm Weather Prediction Center (SWPC) has issued a Geomagnetic Storm Watch from Monday through Wednesday, anticipating potential G3 (strong) solar storm activity on Tuesday. This alert is crucial for power grid, communication, and satellite operators to prepare for possible disruptions. The SWPC forecasts that several coronal mass ejections (CMEs) from the Sun will arrive on Tuesday, with the highest geomagnetic activity expected to occur that day. The Kp-index, which measures geomagnetic activity, is predicted to reach levels of 7 out of 9 on Tuesday, indicating significant storming. The SWPC noted that the most intense solar storming is likely to occur between 8 a.m. and 12 p.m. ET, coinciding with daylight hours for much of the eastern United States. During this period, regions in the northern U.S. and parts of the Midwest may have the opportunity to view the Northern Lights. In addition to the anticipated G3 levels, the SWPC also warned of possible G2 (moderate) storm levels early Tuesday morning. The ongoing solar activity is attributed to several active sunspot regions, which are generating solar flares and associated CMEs. For optimal viewing of the auroras, conditions are favorable in much of Canada and the northern U.S., particularly in areas like Minneapolis, Casper, and Buffalo, where minimal cloud cover is expected. The current lunar phase, with only 20% illumination, will also aid in visibility, making it an ideal time for aurora enthusiasts to observe the natural light display.
