The skies are giving us a Halloween treat- an aurora borealis may spread
across the northern U.S 🤩
New England, the Upper Midwest and the Northern Tier states may see the dancing northern lights on Saturday into Sunday.
Bright auroras may illuminate the dark skies over the northern U.S. this Halloween weekend.
On Thursday, the sun launched a major “X-class” solar flare, sparking a high-frequency radio blackout across parts of South America. That same pulse of energy is trailed by a coronal mass ejection (CME), or a cluster of solar plasma and material surfing an interstellar shock wave.
The CME, the strongest of this solar cycle so far, could slam Earth and whip up a stunning display of the northern lights. A CME from a similar position spawned beautiful auroras on Oct. 12.
NOAA’s Space Weather Prediction Center in Boulder, Colo., is warning of a potential strong (G3) geomagnetic storm that may rock the Earth on Saturday, with effects lingering into Sunday. Storms of that tier can produce displays of the northern lights visible at latitudes as low as Pennsylvania, Iowa and Oregon, and can also have electrical impacts.
Voltage irregularities are possible on high-latitude power grids, along with intermittent issues with radio and navigation.
