Geomagnetic Storms Could Bring Aurora Displays to Lower Latitudes Sunday Night
skywatchers across a wider swath of the United States than usual may be treated to views of the aurora borealis-the Northern Lights-on Sunday and Monday nights. The National Oceanic and Atmospheric Administration (NOAA) predicts the geomagnetic field will reach active levels, with G1 (Minor) geomagnetic storm levels likely from December 7th-8th. this is due to the arrival of a coronal mass ejection (CME) that left the Sun on December 4th.
While the aurora is typically visible in high-latitude regions like Alaska and Canada, this geomagnetic activity could push the auroral oval southward, perhaps making it visible in states as far south as the Midwest, and even parts of the Northeast. The strength and extent of the display will depend on the intensity and direction of the CME’s impact. NOAA reports the influence from a previous coronal hole is waning, but the CME’s periphery is expected to be the primary driver of the upcoming activity.
The best time to look for the aurora will be after nightfall, away from city lights. Observers should look towards the northern horizon. Several factors influence visibility, including clear skies and minimal light pollution.
