#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 03 - 09 August 2020

Solar activity was at very low levels on 03-07 and 09 Aug. Low

levels were reached on 08 Aug as Region 2770 (N23, L=023, class/area Cso/070 on 06 Aug) produced an isolated C1/Sn flare at 08/0349 UTC. This was the first C-class flare observed since 29 May. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate to high levels. Moderate levels were observed on 03-04 Aug. High levels were observed on 05-09 Aug due to coronal hole high speed stream (CH HSS) influence. The maximum flux of the period was 2,815 pfu observed at 05/1630 UTC.

Geomagnetic field activity ranged from quiet to active levels. The period began with the onset of a positive polarity CH HSS. Total field reached 10 nT at the beginning of the period and solar wind

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 CV-International numbers,

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 CV-I, i.e. either 09 or 10 Nov 2019 at Ri 1,46.

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.

PICK FROM SPACEWEATHERLIVE.COM BLOG https://spaceweatherarchive.com/2020/08/04/solar-cycle-25-is-coming-to-life/ Solar Cycle 25 is Coming to Life

AUGUST 4, 2020 / DR.TONY PHILLIPS

August 3, 2020: There’s no longer any doubt. New Solar Cycle 25 is coming to life. The latest sign came today with the emergence of a new sunspot group, AR2770, inset in this magnetic map

of the sun’s surface from NASA’s Solar Dynamics Observatory

Kjell Inge Malde

AUGUST 6, 2020 AT 8:49 AM

Calculating the 10,7cm solar flux 2800 MHz from Penticton, Canada, giving a 13-rotation centered average for the 1AU adjusted values, I have landed on 2019 November 23 as a center minimum date. This correspond fairly well with R-I, CV-I, maximum spotless days on the mentioned values,

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.

There are so far one comment to my own comment:

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.
