NOAA forecasters have issued a geomagnetic storm watch for Aug. 18th and 19th when a series of CMEs is expected to graze Earth’s magnetic field.
Individually, none of the impacts will be particularly direct or strong, but collectively they could cause a G3-class (strong) geomagnetic storm. The primary source of the CMEs, unstable sunspot AR3078, is still actively flaring today. Updates @ Spaceweather.com.
