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 ?

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

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

Re: High latitude sunspot
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,

Re: High latitude sunspot
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

Re: High latitude sunspot
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...

Re: High latitude sunspot
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.Raf

Re: High latitude sunspot
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.
Full Disc showing the new sunspot and its location for comparison:
Resolution difference, 40mm vs 150mm aperture:
Very best,

Re: High latitude sunspot
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.

Re: High latitude sunspot
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.marktownley wrote: ↑Sun Nov 11, 2018 6:54 am It's definitely a cycle 25 spot.

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.

Re: High latitude sunspot
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.

Re: High latitude sunspot
Let's hope it really is the start of cycle 25.

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