Gigantic Coronal Hole in Sun Tweaks Aurora Alert

Earth Sky is issuing an aurora alert for Janaury 4 and 5 due to a large coronal hole in the sun that is facing the earth. According to Spaceweather.com it could mean chances for geometric storms and auroras are high.

Aurora Alert

Increased Chance of Aurora sightings

People living in high altitudes should look forward to an increase in aurora sightings for January 4 and 5. The Space Weather Prediction Center is calling for auroras at 60 degrees N. and further northward. It could also include possible aurora sightings at the latitude of the northern United States – i.e., Michigan and Maine.

Tony Phillips, astronomer and writer for Space Weather, tells us “Coronal holes are regions where the sun’s magnetic field peels back and allows solar wind to escape … Residents of the Arctic should expect G1-class geomagnetic storms and bright auroras in the nights ahead.”

The Aurora Borealis or Northern Lights is an anticipated sight for most earth-folk. Basically, this shimmering-light phenomenon is caused by the sun’s activity. Bands of light, created by supercharged solar particles interact with the Earth’s magnetic fields, creating a spectacular light show.

Phillips assures that we shouldn’t be worried about the geometric storms as they are expected to be minor. Check for updates here.
