定向日冕物質拋射(coronal mass ejections)將在9月22/23號抵達地球

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, 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.

Earth Directed CME Will Arive on the 22nd or 23rd
