Solar eruptions associated with a moderate solar flare are expected to cause auroras visible in northern parts of the United States starting Thursday night into Friday morning, October 9. The National Oceanic and Atmospheric Administration's Space Weather Prediction Center has issued a moderate Geomagnetic Storm Watch due to a coronal mass ejection (CME) departing the sun on Tuesday. While the impacts are mainly manageable, there could be periods of moderate storm activity with minor technological disruptions. Aurora borealis may be visible in areas as far south as New York, Wisconsin, and Washington state during this period.

Story summary
A coronal mass ejection (CME) linked to an M1.4-class solar flare from active region AR4549 on the Sun is heading toward Earth, potentially causing auroras across parts of the United States and Canada around October 8-9. NOAA’s Space Weather Prediction Center has issued a G2 (moderate) geomagnetic storm watch for October 9, with G1 (minor) to G2 conditions expected as the CME reaches Earth at about 560 km/s. The best viewing opportunities are forecasted across Alaska and northern-tier states such as Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Maine, Vermont, and New Hampshire, depending on local weather and darkness.

Multiple solar eruptions could spark auroras across the northern US starting tonight
The ejection is associated with a moderate solar flare.

It's been a busy week for the sun, and aurora watchers in some northern and upper Midwest states looking for a glimpse of the famed colorful sky could benefit from enhanced solar activity Thursday night into Friday morning, Oct. 9.

On Tuesday, a coronal mass ejection (CME), a massive burst of charged particles embedded in a magnetic field, departed the sun bound for Earth.
asserted
ejection → charge → Earth
The ejection is associated with a moderate solar flare.

ejection → associate → flare
The National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC) has issued a moderate Geomagnetic Storm Watch beginning Thursday evening into Friday, as a result of the CME.

According to NOAA, a geomagnetic storm is "a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth."
uncertain
that → accord → Earth
While the agency says much of the activity will be minor, there could be periods of moderate storm activity.
uncertain
much → say → activity
The UK Met Office says there's even a slight chance of strong G3 levels.
asserted
Office → say → levels
The SWPC says the solar activity could create minor impacts to our technological infrastructure, but it's "mainly manageable."
On the bright side, the aurora borealis, which appears in the night sky when electrically charged particles from the sun hit Earth's atmosphere, could be visible in areas that don't normally experience it.
uncertain
that → say → it
"Aurora may be seen as low as New York to Wisconsin to Washington state," SWPC said in its alert.
uncertain
SWPC → see → alert
Another CME linked to a smaller solar flare is also headed toward Earth but is only expected to deliver a "glancing blow" over the weekend, according to the UK Met Office.
uncertain
CME → link → Office
All this solar weather will keep conditions unsettled to active over the next few days.
asserted
conditions → keep → days
But whether you'll be able to see the auroras depends on exactly when the CME arrives, the cloud cover and the magnetic orientation of the CME's magnetic field.
asserted
CME → see → field
When geomagnetic activity becomes stronger, the aurora can sometimes be seen farther south than usual.
