GEOMAGNETIC STORM WATCH (G1): Over the past few days, a series of M-class solar flares may have hurled multiple CMEs toward Earth. In fact, so many CMEs have left the sun since Sept. 20th, analysts are having trouble sorting them out. Somewhere between two and four appear capable of grazing Earth’s magnetic field between Sept. 23rd and Sept. 25th. Minor G1-class geomagnetic storms are possible on all those days.
