Sunspot regions today 24-3-2021

Region / Number of sunspots / Class

2811 5 BXI
2812 1 HSX

2810 without spots

SDO doesn't agree with those figures though ???

Thanks everyone and hopefully will see your images whenever you can Nigella and James

Hi Rainer, https://www.spaceweatherlive.com/en/solar-activity.html is the website I've been using for a while (along with many others), where
the web-linked one shown above, was and still is showing the inclusion of AR2806 with its' 7-spots. I suspect someone there has accidentally included this for whatever reason as the current SDO image at around 2300hrs/24-3-2021 is only showing a total of 4 (or so) spots with AR2811/2812.

I tried checking backwards before 8-3-2021 with my records when AR2806 was around, suggests to me that 2806 is being recorded as a possible return-visit, but certainly not with as many as 7-spots now for itself...

Any other comments welcome.

Within that web-link, where within the "Sunspot Regions" panel further information as "Class Magn. & Spot" of - the question-mark can explain more.
How accurate these two items are:- may or may not be accurate, so I don't tend to utilise those...
SDO is usually very up-to-date (within 30+ minutes of a required-datum and shows enough of what is happening as far as I am concerned...

Rainer I trust that may answer your question ?

Regards
Terry

https://hinode.msfc.nasa.gov/data_archive.html & https://www.lmsal.com/heksearch/ may well provide more intense-data about what is occurring at present and previously on our Sun...

Cheers & Enjoy getting your head around the websites... !!!

Thanks again Eric. Still strange that 2806 has been included on that website, but hey who knows...

See if Rainer can work his magic...

Thanks Mark, Maurits and Alexandra.

That AR2806 overlap-error has now been deleted and 2811 appears to be degrading at mid-day today.

Cheers
Terry
