On Tuesday an enormous coronal mass ejection occurred on the Sun and is heading straight for us. The coronal mass ejection was observed “just upstream of Earth” at 2:32 p.m. ET, according to an update from NASA this afternoon. The agency says it’s too early to tell how the CME’s magnetic structure might affect the planet.
But NASA’s Space Weather Prediction Center also notes, “Aurora watchers may be in luck for tonight. The ongoing Solar Radiation Storm, currently at S2 (Moderate) levels, is seeing a modest enhancement with this shock passage.”
The agency says to expect S3 (strong) geomagnetic storm activity tonight and tomorrow.
