Solar Storm Watch in Effect for February 15, 2018

Solar Ham — A coronal hole solar wind stream is predicted to reach Earth by February 15th. In addition to this, a weak coronal mass ejection (CME) observed early on February 12th is expected to possibly reach Earth within the same period. The combined effects could generate minor (G1) storming at higher latitudes with a chance for isolated (G2) storming as well. Sky watchers should be alert for visible aurora towards the end of the week. (source)

SUNSPOT EXPLODES, HURLS CME AT EARTH: On Feb. 12th, the magnetic canopy of sunspot AR2699 exploded–for more than 6 hours. The slow-motion blast produced a C1-class solar flare and hurled a coronal mass ejection (CME) almost directly toward Earth. This movie from the Solar and Heliospheric Observtory (SOHO) shows the CME leaving the sun:

The CME could arrive as early as Feb. 14th, although Feb 15th is more likely. NOAA forecasters say there is a 60% chance of G1-class geomagnetic storms with isolated periods of stronger G2 storming.

The effectiveness of the CME could be enhanced by a stream of solar wind that was already en route to Earth when the sunspot exploded. The solar wind is flowing from a large wedge-shaped hole in the sun’s atmosphere. If the approaching CME sweeps up material from that stream, snowplow-style, it could strike Earth’s magnetic field with extra mass and potency. (source)
