Aeon Posted May 18, 2020 Share Posted May 18, 2020 @Ron NLI followed the trend of these proto-sunspots for a few days, I think the reason why they are not counted is because the real sunspots are not yet visible. Perhaps they have already formed behind the Sun and are weakening or still developing. Let's wait and see. Link to comment Share on other sites More sharing options...
Ron NL Posted May 18, 2020 Author Share Posted May 18, 2020 (edited) This pic taken from sdo-nasa just now 18-05-2020 @ 22:33 gmt is that REAL sunspots or not ? ..yes they dont look like the other representation you usually see (dark spots) Actually i wish to know if there is Solar-Activity right now .. everywhere they say the nr of sunspots are supposed to be a representation of that i dont see any dark-spots ...and everywhere on the net they say 0-sunspots right now, but i clearly do see solar-activity in above picture (HMBI) ... my conclusion the sunspot as a measure of solar-activity SUCKS ! More here (last 48 hours in various wavelengths) https://sdo.gsfc.nasa.gov/data/dashboard/?d=HMIB;1600;1700;0193;0171;HMIBC they all show solar-activity for almost 2 days now or do they not ? ...so where are the sunspots ?

Ron NL Posted May 18, 2020 Author Share Posted May 18, 2020 (edited) . To add to the cunfusion ... below article on space.com talks about "SUNSPOTS" ... and they use the same kind of picture in HMBI format (magnetic activity) as i did above https://www.space.com/sun-weather-overlapping-solar-cycle-active-regions.html So according to space.com ... you can see sunspots by looking at magnetic activity (spots/areas/intensities) its just another representation of them ... or at least it represents a part of it Question: if even space.com shows a (HDMI format) pic and calls it a sunspot (or a representation of it) then why is it that: i look at realtime pics of the last 2 days which clearly also show large (HBMI) sunspots that all counters on the web (including on this website here) say: NR of Sunspots = 0 ..... ??? . .

Jesterface23 Posted May 18, 2020 Share Posted May 18, 2020 @Ron NL I think this is going a bit off topic of the topic. But, the images you are posting are the magnetic structure of the region. Intensitygram imagery(HMIIF/HMIIC) is the imagery you want to look at to see sunspot regions, https://sdo.gsfc.nasa.gov/assets/img/latest/latest_4096_HMIIF.jpg.

Aeon Posted May 18, 2020 Share Posted May 18, 2020 @Ron NL These are magnetic fields that form on the surface of the sun. They produce visible sunspots only if sufficiently intense. However, as long as the dark spots are visible, they are not counted as sun spots. Link to comment Share on other sites More sharing options...

Spotless plages are no sunspot regions. Sunspots get numbered by the SWPC during their solar observation hours, so there will always be moments when there are new regions that have emerged that get numbered during the day. Only visible regions will be numbered, spotless plages are never counted. On the magnetogram you’ll always see the magnetic layout of visible regions and spotless plages. 1 Link to comment Share on other sites More sharing options...
Drax Spacex Posted May 20, 2020 Share Posted May 20, 2020 (edited) A "sunsplotch" isn't necessarily a "sunspot." This is a good example how 0 sunspots doesn't imply an absence of interesting, trackable solar structure and activity.
