INCOMING CME: NOAA forecasters estimate a 25% chance of strong geomagnetic storms around the poles on April 8-9 when a CME delivers a glancing blow to Earth's magnetic field. The cloud was propelled in our direction by a solar filament, which erupted on April 5th (movie). High-latitude sky watchers should be alert for auroras. Aurora alerts: text, phone.
ANOTHER ERUPTION: For the past few days, magnetic filaments have been rising and snapping all around the sun. The latest eruption occurred during the late hours of April 7th, [and was captured] in an extreme UV video from NASA's Solar Dynamics Observatory. A CME hurled into space by this eruption might deliver a glancing blow to Earth's magnetic field on or about April 9th. Like a CME observed two days ago, this one was visually confused by two other clouds leaving the sun from other blast sites at about the same time: movie.
