GEOMAGNETIC STORM WARNING: NOAA forecasters have modeled the trajectory of yesterday's CME and confirmed that it will likely arrive on Oct. 11th.

The impact could spark G1 to G2-class geomagnetic storms. If a moderately-strong G2-storm materializes, sky watchers in the United States could see auroras as far south as a line connecting New York to Oregon.
