The aurora borealis is anticipated to be visible on August 7 and August 8 across 18 states as a result of geomagnetic storm conditions from an incoming coronal mass ejection (CME). NOAA warns that moderate to minor geomagnetic storm levels could occur, leading to potential aurora sightings. Northernmost states, including Alaska and North Dakota, have a higher likelihood of visibility. Observers are advised to find clear northern vantage points to enhance their chances of seeing the colorful display in the night sky.
"A CME and Coronal Hole High Speed Stream (CHH SS) are anticipated to affect Earth with elevated geomagnetic response and dependent upon the orientation of the embedded magnetic field, potential exists for moderate storm levels," the NOAA said in a statement on their website.
"Combined effects from a coronal mass ejection (CME) which lifted off the Sun on 05 Aug and a coronal hole high speed stream (CH HSS) are expected to cause geomagnetic storming on 08-09 Aug. A G2 (Moderate) watch was issued for 08 Aug with the onset of activity."
"Even a minor disruption caused by the CME could trigger the aurora borealis. The exact timing of the disruption is unclear, so the potential aurora borealis could be visible any time between 11pm on Aug. 7 through Aug. 9."
"For residents of those states, the best way to maximize the chances of seeing the aurora borealis is to find a north-facing vantage point that lets you see the horizon clearly."
