A SUNSPOT BIG ENOUGH TO SEE FROM MARS:

NASA's Mars Perseverence rover looks at the sun once a day to check the air for dust. A dim sun = lots of dust. Over the weekend, the rover found a large sunspot. This animation shows the behemoth crossing the solar disk Aug. 17th through 20th:

Perseverance's images of the sun come from its MASTCAM (stereo mast camera), which puts about 90 pixels across the solar disk. It takes a large sunspot to show up in these low-resolution images. Because Mars is orbiting over the farside of the sun, Perseverance can see approaching sunspots more than a week before we do. Consider this your 1-week warning: A big sunspot is coming.

Nice find!

Nice find!

I originally saw (and posted) an article from the Daily Mail but it was totally histrionic and major doomer porn about how earth's power grids could be knocked out next week (!) so deleted it when I saw the link (as I posted) to the more calm and scientific spaceweather post . Here's a link to the Daily Mail article if you're curious how they reported the story, not going to post it now that I found a more rational presentation of how they can see sunspots on the far side of the sun from Mars, which is what interested me in the story in the first place! We've seen so many of these large far side sunspots that diminish as they turn over to our side of the sun that I'm not going to worry about this one ... unless it starts spewing off large earth facing CME's which would of course grab my attention.

Experts predict the sunspot will continue to grow as it moves across the sun's surface to a region that faces Earth. The event could see solar storms that knock out power grids on our planet.

One of the space weather groups I follow on Facebook and YouTube said NASA had given a warning for that next week, but they don't know if there will be a flare or if it would even be earth facing that far in advance.
