GEOMAGNETIC STORM WATCH--UPGRADED: This weekend's geomagnetic storm watch has been upgraded from G2 (Moderate) to G3 (Strong). Why? Because giant sunspot AR3664 keeps hurling CMEs toward Earth. There are now at least 3 storm clouds heading our way. See how many you can count in this 24-hour movie from the Solar and Heliospheric Observatory:
A NOAA forecast model predicts the first CME will reach Earth late on May 10th. Additional CMEs will arrive on May 11th and possibly 12th. Minor to strong geomagnetic storms could occur on all three days, with auroras potentially visible at mid-latitudes in Europe and the USA.
