Between October 11 and 13, the Sun unleashed a torrent of coronal mass ejections (CMEs). Now, these powerful bursts of solar plasma and magnetic energy are on a collision course with Earth.<\/p>\n

Space weather forecasters expect them to arrive tonight and cause the northern lights\u2014or Aurora Borealis\u2014to stretch farther south than usual. NOAA\u2019s Space Weather Prediction Center issued<\/a> a G2 (moderate) geomagnetic storm watch for Thursday, October 16, with the strongest impact expected between late Thursday night and Friday morning.<\/p>\n

Geomagnetic storms\u2014major disturbances in the Earth\u2019s upper magnetosphere\u2014cause aurora to become brighter, more active, and move farther away from the poles. NOAA\u2019s aurora forecast for tonight shows<\/a> 15 states above the aurora view line, meaning they have a decent chance of seeing the northern lights.<\/p>\n

Those states include Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York, Maine, New Hampshire, Vermont, Wyoming, and Iowa.<\/p>\n

If you\u2019re hoping to catch a glimpse of the aurora tonight, make sure to choose a viewing location with minimal light pollution, a clear view of the northern horizon, and cloudless skies. The best time to look up is between midnight and 2 a.m. local time, when skies are darkest.<\/p>\n

What\u2019s causing this geomagnetic storm? <\/p>\n

It\u2019s been a wild week for solar activity. Sunspot region AR4246\u2014a large, complex, and active grouping of sunspots\u2014has been firing off a barrage of M-class (medium-sized) solar flares. One of these flares, which erupted on October 13, is associated with one of the CMEs currently heading toward Earth.<\/p>\n

When an Earth-facing sunspot\u2014a cooler region on the Sun\u2019s surface caused by a concentration of magnetic field lines\u2014produces a CME, the ejected material hurtles toward our planet at breakneck speed. Once it reaches Earth\u2019s magnetic field, the influx of charged particles and energy can trigger a geomagnetic storm.<\/p>\n

Depending on its severity, a geomagnetic storm may increase the likelihood of visible auroras, disrupt power grids, satellites, and other infrastructure, and cause radio blackouts.<\/p>\n

What to expect from this G2 storm <\/p>\n

The arrival of multiple CMEs in quick succession tonight could result in a \u201cstacked\u201d impact. This compounding effect can intensify a geomagnetic storm\u2019s strength and duration, making it more likely to disrupt technology and produce auroras at lower latitudes than usual.<\/p>\n

That said, forecasters aren\u2019t anticipating any severe impacts from tonight\u2019s storm. In addition to helping the aurora appear a bit farther south, it may cause some manageable disruptions to technological infrastructure, according to NOAA.<\/p>\n

Still, geomagnetic storm impacts are difficult to predict due to the complexity of the Sun\u2019s processes and the evolving nature of CMEs. There\u2019s always a chance that an oncoming storm could be stronger\u2014or weaker\u2014than anticipated. But for folks in the northern U.S. hoping to see some dazzling aurora this week, it certainly looks like tonight is the best chance.<\/p>\n","protected":false},"excerpt":{"rendered":"Between October 11 and 13, the Sun unleashed a torrent of coronal mass ejections (CMEs).
