Stormy for your 4th of June as Earth is impacted by a coronal mass ejection this evening. A Minor Geomagnetic Storm Watch is in effect for June 4.

SOLAR STORM MAY IMPACT EARTH FRIDAY: Earth may be grazed by a coronal mass ejection sometime Friday as infamous Active Region 3697, (formerly 3664) continues to impress with high activity. This afternoon saw yet another X-class solar flare and impressive coronal mass ejection which appears wide enough that a portion of it could be Earth-directed. If so, we could see minor (Kp=5, G1) or moderate geomagnetic storm (Kp=6, G2) levels late Friday. In the first picture, this NOAA/SWPC model run indicates that Earth may be grazed by the far flank of the CME late in the Zulu day on the 31st. Notice the increase in the green traces representing the near-Earth environment in the plasma density and radial velocity curves. The two large blue circles on the far left side represent top-down views of the heliosphere's density and velocity as if you were looking down from above the Sun. The Earth is the small green circle. Notice the extent of the large red crescent in the model output--this is the CME. The second picture is a picture of the CME in NASA's SOHO coronagraph imagery--the Sun's intense light is blocked out by an occulting disk so that the solar storm can be seen admist the Sun's corona, or outer atmosphere. #spacewx @spacewxwatch
