#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 02 - 08 August 2021

Solar activity was at very low levels. An isolated C1 flare peaked

at 09/0004 UTC just after the reporting period from new Region 2853 (N23, L=192, class/area Axx/010 on 08 Aug). The single spot just appeared late on 08 Aug but was preceded by an area of active plage which rotated onto the visible disk on 06 Aug. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 04-05 Aug with a peak flux of 1,570 pfu observed at 05/1725 UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor) geomagnetic storming. An enhancement in the IMF field began at 02/0900 UTC, likely from a glancing blow from the 28 Jul CME. Total

The above graph shows the deveopment in average lifetime of sunspotregions.

Lifetime today: 6,91 days average = 84,2% of max Lifetime 01.03.1993 which was 8,21 days.

News July 2021

Solar activity is still low but number of regions are slowly increasing.

As shown in this issue, the CV as 13-rot. centered averages are now higher than for solar cycle 24 at the same time of progress from minimum!

There were a total of 12 sunspot regions developing in July 2021.

The above mentioned regions were the 4 only out of 12 regions appearing in July.

Especially from the 1st until the 7th there were according to NOAA multiple C.class flares that was produced. They mainly came from regions 2835 and 2838.

In combination with region 2842 this was also the case on the 20th. Large filaments were observed on the 11th and 31st.

Region 2844 (S43-138-rot 2246) was a very rare sunspotregion,

a small HAX that lived for three days only but surrounded with active faculae. The extreme latitude of this region are only superceded by 7 regions

in history 1982 until today.

The last time this happened in the sun's southern hemisphere was in late June 2001 when two regions appeared at S48.

The last time it happened on the northern hemisphere was in May 2010 when a region appeared at N42 latitude.

From 15 August 1981 until 18 July 2021 the totals are:

NORTH 4310 regions (47% of all) average latitude 15,16 heliographic degrees SOUTH 4917 regions (53% of all) average latitude 15,42 heliographic degrees

We wish you all lots of sunny days, happy observing and good luck further on in 2021!

Please remember you are always welcome to contribute with drawings and photos!
