Sun ejects CME directed towards Mercury and Venus
The sun erupted with a coronal mass ejection or CME on July 1, which soared off in the direction of Mercury and Venus.
Washington: The sun erupted with a coronal mass ejection or CME on July 1, which soared off in the direction of Mercury and Venus.
CMEs are a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites.
Experimental NASA research models based on NASA`s Solar Terrestrial Relations Observatory show that the CME was not Earth-directed, and it left the sun at around 570 miles per second.
The CME may, however, pass by NASA`s Messenger, Spitzer and STEREO-B satellites, and their mission operators have been notified.
There is only very slight particle radiation associated with this event, which is what would normally concern operators of interplanetary spacecraft, because the particles can trip computer electronics aboard interplanetary spacecraft.
If warranted, operators can put spacecraft into safe mode to protect the instruments from the solar material.
