The Solar Dynamics Observatory (SDO) observed the flare’s peak at 1:41 a.m. EDT (06:41 UTC). SDO recorded these images (above) in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material — at temperatures less than 80,000 K.
The CME should deliver a glancing blow to Earth’s magnetic field during the late hours of June 8th or June 9th. High-latitude sky watchers should be alert for auroras when the CME arrives.
