yeah how come the count isnt 236 today? i think it will correct in time, ive seen this happen before.

Yeah, I think they  will, or should do

Another cycle 25 sunspot has appeared sadly.

tci=37.9 billion watts

neutron count=8.6%=high

kp index=0 for next 24 hours so flatlining, further cooling of thermosphere and extra cosmic rays coming in.

Solar cycle 25 is on the way!

Did yesterday's spot get counted? Was its polarity SC25? Thanks

Yes, looks like it.  Apparently it was SC25.

Yeah, as mentioned previously reverse polarity SS's based on prevailing cycle are not unusual. Some of it, I understand an indicator is which hemisphere and latitude within that hemisphere. I think.

yes indicators that solar cycle 25 is getting ready to rev up. an analogy: it takes a year to 18 months to get ready for a marathon. solar cycle 25 might not get going until april or possibly september, its anyones guess, but 2020 could have a big sunspotless count.

THE MAGNETIC AFTERGLOW OF A SOLAR WIND STREAM: This weekend, Arctic skies turned green as a minor stream of solar wind buffeted Earth's magnetic field. Chris Hodgson photographed the geomagnetic glow on Nov. 17th from Abisko, Sweden:
