Farside sunspot that blasted mars a few weeks ago

[Jay-B]

I'm wondering when we will see the sunspot that hit mars a few weeks ago. Shouldn't that area be turning into view soon?

I was completely unaware of this.   Elon Musk our favorite Martian is currently earthbound and he is probably preoccupied anyway. Whats up? @Jay-B??

@tniickck a sunspot can travel 180 degrees in 12 days?

Near the equator the Solar rotation rate is once every ~24.5 days, around 40° of latitude it's once every ~28.5 days or so, so spots in between, which is where more spots are now, will take somewhere between those two times to rotate. There is some drift too I believe, but I'm not sure how much that is, I doubt it's more than a few degrees per rotation at most, maybe someone else knows.

So yes, ~180° of longitude in ~12 days isn't very far from the actual numbers, but it's probably closer to ~160° in that time; however, that image is from 00:00Z on that day, so it's actually closer to 13 days now, so somewhere around ~170° since then.

For reference, a Carrington rotation is defined as occurring every 27.2753 days.

Interesting for sure.  And looks solid. But at least once before we were sadly disappointed when they were due.  I’m not seeing much currently as far as incoming regions. But a hint of something north in 131 now.  Time will tell as always.  Thanks for posting this btw.  Edit!   Obviously I missed the prior posts. Haha.
