SOLAR ACTIVITY UPDATE: Incoming CME, glancing blow to Earth on Sept. 22t...



FOUR CMEs: On Sept. 19th, the STEREO-SOHO fleet of spacecraft surrounding the sun detected six coronal mass ejections (CMEs). Two of the clouds rapidly dissipated. The remaining four, however, are still intact and billowing through the inner solar system. According to analysts at the Goddard Space Weather Lab, who prepared the movie, one CME should hit Mercury on Sept. 20th at 05:40 UT while another delivers a glancing blow to Earth's magnetic field on Sept. 22th at 23:00 UT. All impact times have an uncertainty of plus or minus 7 hrs.
