The Sun began its Labor Day celebration late Saturday, September 4 around 1600 UT, with a magnetic filament erupting from active region 1103, hurling a bright coronal mass ejection (CME) off the Sun's northwestern limb. The CME was not directed at Earth, although the CME cloud could deliver a glancing blow to Earth's magnetic field, which may result in a few high-latitude aurora.
