NOAA forecasters have boosted the odds of polar geomagnetic storms on Jan. 4th and 5th to 65% as a stream of solar wind approaches Earth. The hot wind is flowing from a large hole in the sun’s atmosphere. This image, from NASA’s Solar Dynamics Observatory, shows the yawning structure almost directly facing Earth on Jan. 3rd:
Coronal holes are regions where the sun’s magnetic field peels back and allows solar wind to escape. The stream of wind emerging from this coronal hole recently blew past NASA’s STEREO-A spacecraft with peak speeds exceeding 700 km/s. Similar high speeds are likely when the stream reaches Earth on Jan. 4th and 5th
Residents of the Arctic should expect G1-class geomagnetic storms and bright auroras in the nights ahead. http://spaceweather.com
