Overview

• NOAA’s Space Weather Prediction Center posted a strong G3 watch for October 2, raising the likelihood that auroras will be seen well beyond their usual range.
• Forecasters highlight potential visibility across much of Alaska and the northern tier of the U.S., with reports also pointing to chances in states such as New York and northern Illinois if conditions cooperate.
• Ahead of the G3 watch, NOAA flagged a moderate G2 setup for Wednesday with a Kp index near 4, supporting continued, brighter activity into the evening.
• Local outlets report a fourth consecutive night of auroras across Canada and northern U.S. states, with displays expected to occur off and on overnight depending on substorm timing.
• The current activity is linked to high-speed solar wind from coronal holes, which can intensify auroras and cause minor disruptions to satellites, GPS, and radio; best viewing is from dark locations between about 10 p.m. and 2 a.m.
