It seems likely that AR1618 flare activity will continue through Thanksgiving, and if you live at high latitudes, you may be lucky enough to see some Thanksgiving Day aurorae. The sun is currently bathing our planet in a moderate-speed stream of solar wind. Although a full-blown geomagnetic storm isn’t expected, there’s a chance of some heightened auroral activity near the Arctic Circle.
Monster Sunspot To Unleash Powerful Solar Flares
The huge sunspot complex measures more than 60,000 miles across — big enough for amateur astronomers with decent equipment to spot from their backyards, weather permitting.
Monday evening’s eruption from AR 1471 apparently generated an Earth-directed CME, which should hit Earth sometime Wednesday morning (May 9) Eastern time, researchers said.
A massive solar flare is unleashing a tremendous storm that could disrupt satellites and power grids.
Yesterday’s solar flares erupted from the giant active sunspot AR1429, which spewed an earlier X1.1-class flare on Sunday (March 4). The CME from that outburst mostly missed Earth, passing by last night at around 11 p.m. EST (0400 GMT March 7), according to the Space Weather Prediction Center, which is jointly managed by NOAA and the National Weather Service.
This means that the planet is already experiencing heightened geomagnetic and radiation effects in advance of the next oncoming CME.
INCOMING! Sun Blasts Another CME at Earth and Mars
You may not know it, but there’s an epic magnetic battle between the sun and Earth raging over our heads.
Over the weekend, the Earth’s magnetic field was struck by a coronal mass ejection (CME). The CME — a vast bubble of solar plasma that had erupted from the sun on Jan. 19 — took longer than expected to travel through interplanetary space, but on Sunday it made contact.
All predictions suggested the CME would likely hit us on Dec. 28 (Wednesday) and it appears that is going to happen.
Depending on the orientation of the magnetic field wrapped around the CME bubble of highly charged solar particles when it hits the Earth’s geomagnetic field, there will be a chance of some auroral activity.
