CMEs Heading Toward Earth
STRONG SOLAR ACTIVITY: On Sept. 6th, active sunspot 1283 produced two major eruptions including an impulsive X2-class solar flare. The blasts hurled a pair of coronal mass ejections (CMEs) toward Earth, which could spark geomagnetic activity when they arrive on Sept. 8-10. High-latitude sky watchers should be alert for auroras in the nights ahead.
The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, the two eruptions hurled clouds of plasma (CMEs) in our direction. CME impacts, geomagnetic storms and auroras are expected on Sept. 8-10.
This week's sharp increase in solar activity has turned the sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283.
