UPDATE : TheNorthern Lightscould be visible in the U.S. tonight ( March 26 ) , appearing as far to the south as New York and Idaho due to a " coronal hole " post streams of charge particles toward Earth .
The National Oceanic and Atmospheric Administration ( NOAA ) initally issued a G2geomagnetic storm warningfor Tuesday , March 25 , which hasnow been hold out into Wednesday(March 26 ) .
Bright auroras could be visible tonight (Tuesday) in the Northern U.S. as Earth passes through a corridor of charged particles leaking out of a “coronal hole” in the sun’s atmosphere.
Like hurricanes , geomagnetic storms observe a 5 - point severityscale . G2 storms are considered " moderate " in strong suit and could get small-scale technological disturbance such as radio blackouts , GPS malfunctions , and an increase chance of blemish auroras at scurvy latitudes than usual .
" Watches of this horizontal surface are not uncommon , " according toNOAA ’s Space Weather Prediction Center ; G2 - strength geomagnetic storms hit Earth about 360 days in each 11 - yr solar cycle . These storms can sham space vehicle orbits and cause light tycoon grid fluctuations at high latitudes , but they mostly get " realizable result to some technological base , " accord to NOAA .
The Space Weather Prediction Center issued the extended tempest warning because a " coronal jam " on the Sunday is facing Earth . Coronal holes are cooler , dark region of the sun ’s outermost standard atmosphere ( the aureole ) that are less dense than normal , allowing high - f number solar nothingness — stream of charged particles — to escape from the Sunday and gush outwards into place . Currently , one of these escape mellow - speed streams is pointed directly at Earth .
On March 26, a “coronal hole” will face toward Earth, sending high-speed solar winds in our direction.

Earth’smagnetic fielddeflects most of the solar twist , but some charged corpuscle make it through into the upper layers of the atmosphere . When the solar flatus hits Earth ’s atmosphere , charged particle shoot toward Earth ’s pole , agitating atmospheric molecules along the way and force them to emit Energy Department in the anatomy of colorful auroras .
In October 2024 , the sun reached itssolar maximum time period , the most active part of its 11 - year cycle . During this period , the sun ’s magnetic poles flip , and quad conditions consequence like geomagnetic storm and solar flares pass more frequently . Scientists predict that the solar uttermost will continue for at least a few more months if not longer , providing additional opportunity to blemish the Northern Lights .
