High latitude sunspot

It's raining here (since three weeks...) :( but browsing SDO images a high latitude spot is present, maybe belonging to the 25th cycle. Has anyone already imaged it ?

Good news, Raf. GONG shows that active region: the Mauna Loa view seems to be the best at this time, in my opinion.

All clouds for me :(

Very best,

It certainly could be a new cycle 25 sunspot as the SDO Magnetogram appears to show reversed polarity compared to cycle 24.

The minor active region earlier this week was also high in latitude.

This makes the 4th or 5th feature that points towards cycle 25 coming up soon.

Very best,

sounds crazy, but, i beleive this sunspot emerged because gravitational affect in the solar system from a comet or asteroid. (46P/Wirtanen)

Everytime a comet draws nearer to its close approach to the sun, the spots magically appear. Same with asteroids.
(on the night of 08/09 November, Comet 38p will lie very close to deep sky object NGC 2392 (The Eskimo Nebula) separated by just 8 arcmins)

This is a pattern i have noticed over the course of 8 years.


There is a comet expected to be at perihelion on december 12th ((46P/Wirtanen)), making its closest approach to earth on december 18th.

Due to the nature of these large rocks, they tend to always show up as duos, triples and quadruplets. So right now, there is likely an undiscovered asteroid lurking right now in our solar system doing its gravity thing on the sun, we will only learn about it right after it swings past earth. Maybe around jupiter.

The comet is forecast to be naked eye. I bet money there will be a decent sunspot group up to that very week december 12th-18th, a notable coronal mass ejection and also a significant earthquake..

not so crazy. exactly as I said, it turns out there are three asteroids and they made it to the news...

Very interesting and exciting news. I think from now on we need to show the magnetogram image of the same time as this is the only way to identify the cycle change if the poles are reversed from Cycle 24 :hamster:

I have recorded a high latitude spot in august 2018 (20180804)

This is not the first time that a high latitude AR is recorded

raining here as well...

I remember that spot, it was actually at even higher latitude (+36°) however as it appeared already close to the W limb the magnetic pattern was unclear, may be the N pole is preceding but I am not sure

Thanks Alexandra for the comparison box.

It's a wee dipole. Definitely a sunspot. I was able to resolve both umbra with a 150mm aperture this afternoon between clouds, around 1:30pm Eastern Time (Florida). Still not designation number, that I'm aware of yet, but it's a sunspot I'm confident.

It's definitely a cycle 25 spot. Take a look at the graph from Belgium, it's starting to uptick quite quickly once we get into the new year.

Thanks Mark, for your note. It makes us optimistic - we will see more sun spots and active areas soon, may be for a next warm season in the nothern hemisphere.
See what kind of beauty was on the sun just a two and half months ago! And this was just before the very minimum (from now to a spring)!
I will be quite happy if the next summer we will see such beauties again.

I think once we get into spring we will start seeing the return of the spots in the northern hemisphere again. Cycle 24 the northern hemisphere peaked a good year and half before the southern hemisphere peaked, so, would be reasonable to assume this asymmetry in the start of 25, and seeing spots in the northern hemisphere first is what would expect.

Let's hope it really is the start of cycle 25. :)

Thanks, Mark, graph is very clear. I put my Wolf numbers in a graph too, the overall (N + S) double peak is apparent
