News July 2020
HAS SOLAR CYCLE 24 FINALLY ENDED? Yes.
The lowest solar flux adjusted center averaged 13 rotations indicate 23 Nov 2019 as the approx. min. date. The low level did not reach as low as for transition solar cycles 23 and 24, at 67,93 on 01 Nov 2008.
This time, the cycle transition occurred on 23 Nov 2019 at pfu 69,02, same calculation as above. Now, using the same calculation scheme as above on our
we end up as 10 Nov 2019 as the minimum date with cv 0,48.
Using the other commonly used Relative numbers we end up with the same date as above
Between 12 and 20 Dec 2019 it may seem we made the maximum number of spotless days ending up at 255 days with definate days under cv=0,5.

Calculating the 10,7cm solar flux 2800 MHz from Penticton, Canada, giving a
and also some of the various measurements done by Nobeyama in Japan. All indices should indicate solar cycle 25 has well entered the front door.

SOLAR CYCLE 25 IS HERE! |
Region 2767 taken from SOHO on 28 Jul 2020 at 1330 UTC. Postioned at S22 long. 197 in rot. no. 2233,
yet another region in the solar cycle 25 history,
and covered an average of 80 mvh on the 13 days from E to W. It was classified at HSX for the entire period.
The SOHO picture from 28th July also reveals the upcoming region 2768 in the NE. Regions stable and unremarkable but numbers may be picking up again now. Hopefully no more blank days?
Many plages, one very large, appeared on the solar disk during July, but very few of them evolved into spots.
Please feel free to send in your images for publication here!
Thank you.
