Sunspot has Almost Doubled in Size Since Sunday…..
Sun Unleashes Powerful X-Class Solar Flare
From the article:
A monster solar flare erupted early Sunday (Oct. 19) from a huge sunspot that may just be getting warmed up.
The sun fired off an X-class solar flare — the most powerful type — that peaked at 1:01 a.m. EDT (5:01 GMT) Sunday. NASA’s Solar Dynamics Observatory (SDO) spacecraft captured photos and video of the intense sun storm, which researchers classified as an X1.1 flare.
And speaking of sunspots….
While my son was taking my granddaughter to school this morning it was foggy. Looking up at the sun, through the fog…. he noticed that he could see a dark spot. He told me that he thought that was really strange. Not only could he see it, but my granddaughter did too.
The following pdf talks about conditions that allow you to see sunspots with the naked eye. Pretty interesting stuff.
