CHANCE OF STORMS THIS WEEK: A CME launched by yesterday’s slow-motion solar flare (described below) is expected to pass near Earth on June 15th. Geomagnetic storms are possible if the CME makes contact. NOAA forecasters say minor G1-class storms are likely, with a chance for G2 (moderate) and a slight chance of G3 (strong) storms. Aurora alerts: SMS Text

LONG-DURATION SOLAR FLARE AND CME: Growing sunspot AR3032 exploded on June 13th (0407 UT), producing an M3-class solar flare that lasted nearly 8 hours from beginning to end. NASA’s Solar Dynamics Observatory recorded the slow-motion blast:

NOAA analysts have determined that the CME will pass near Earth later this week, possibly delivering a glancing blow to our planet’s magnetosphere. Their simulation suggests an arrival time of 0900 UT on June 15th. Minor G1-class geomagnetic storms are likely if and when the CME makes contact

Potential Impacts: Area of impact primarily poleward of 60 degrees Geomagnetic Latitude.
Induced Currents – Weak power grid fluctuations can occur.
Spacecraft – Minor impact on satellite operations possible.
Aurora – Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.
