March 14 (UPI) -- A solar storm is headed for Earth, and is expected to collide with the magnetosphere above the Northern Hemisphere on Wednesday and Thursday. But the latest forecast from the National Oceanic and Atmospheric Administration, or NOAA, suggests the storm is likely to be mild.
On Tuesday, NOAA's Space Weather Prediction Center issued a minor geomagnetic storm watch for March 14 and 15. Forecasters estimated the strength of the storm at G1, the lowest rating. A G5 storm is the strongest.
