Weekend Skywatch Alert: Blood Moon Eclipse, Auroras & Shooting Stars Collide (Sept 6–7, 2025)
If you live in mid to high latitudes, you could be in for a treat this weekend: the Northern Lights might come out to play. Space weather forecasters at NOAA’s Space Weather Prediction Center have issued a G1 geomagnetic storm watch for September 6–7 due to a high-speed solar wind stream buffeting Earth’s magnetic field earthsky.org. This solar wind surge comes from a “positive polarity” coronal hole on the Sun – essentially an open magnetic gap in the Sun’s atmosphere unleashing fast-moving particles toward Earth dailygalaxy.com. NOAA has classified the event as a G1 storm with an expected Kp index of 5, meaning auroras could dip much farther south than usual dailygalaxy.com.
