This animation shows the probably progression of the approaching storm:
According to the forecast track ready by analysts at the Goddard Space Weather Lab, the CMEs will also hit Venus on June 15th and Mars on June 19th. Due to the fact Venus and Mars do not have global magnetic fields to defend them, both of those planets will probably shed tiny amounts of atmosphere when the CMEs strike.
Right here on Earth, the influence is likely to trigger a geomagnetic storm around the poles. High-latitude sky watchers should be alert for auroras on June 16th.

On June 14th, for the second day in a row, sunspot AR1504 erupted and hurled a CME toward Earth. The fast-moving (1360 km s) cloud is expected to hit our planet’s magnetic field on June 16th at 14:00 UT, possibly sparking a geomagnetic storm. High-latitude sky watchers should be alert for auroras. Active sunspot AR1504 erupted on June 13th at 1319…

On June 11 the report was benign. SHAPE-SHIFTING SUNSPOT: As it pops and crackles with low level solar flares, sunspot AR1504 is rapidly evolving. During the past 24 hours the active region has shape-shifted from an irregular dumbbell into a dark ring of magnetism wide enough to circumscribe a half-dozen planet Earths: On June 12 the situation on…
