Gashes, Cracks and....Nonsense?

After receiving this SpaceWeather.com link from a few people, I did a quick check around and found that Nasa carried an article about this sort of cracks which occurred in 2003:

Such cracks seem to be quite common. Can they assist in anchoring the uber-intense energy waves? I wouldn't be in the least bit surprised if they could ;)

Meanwhile, there's this humongous "gash" that ripped open on the Sun's surface, courtesy of SpaceWeather.com again (image above):
A GASH IN THE SUN'S ATMOSPHERE: A canyon-like hole has opened in the sun's atmosphere, and it is spewing a broad stream of solar wind toward Earth. NASA's Solar Dynamics Observatory is monitoring the structure, shown here on March 13th.

This is a "coronal hole"--a region where the sun's magnetic field opens up and allows solar wind to escape. Coronal holes appear, in various shapes and forms, several times each month. This one is unusually wide, stretching more than 800,000 km across the face of the sun.

NOAA forecasters say there is a 55% chance of G1-class geomagnetic storms when the solar wind stream arrives on March 14th or 15th. G1-class storms are relatively minor and have little effect on satellites and global power grids. However, they can disorient animals that migrate using magnetic cues at high latitudes and usually spark bright auroras around the Arctic Circle.
Finally, Suspicious 0bservers say that no havoc-causing Solar storm is approaching, it's "nonsense" :


  1. There is also an article on Spaceweather.com this morning saying that reports of some massive incoming solar storm are fake news.

    1. Hi Suzanne, I'm going to cover all bases since I'm uncertain about what you mean. The Solar Flash and solar solar storms are two entirely different things :) I think there's an assumption that the two are the same thing.
