Selected Solar Observations
Monty Leventhal OAM
The first observation was made on the 3rd June due to bad weather and on that day four sunspot groups were seen.
First was a single Hsx spot in AR13026, then a Cri group in AR023, a Cso group in AR024 & a Csi group in AR027.
These groups had no potential to produce Flare as the spots were too small & faint.
Three Filaments were also seen marked in blue & a Prominence on the NW limb reached a height of 74,000km. Two areas marked in orange was Plage.
A new single Axx spot was observed on the 5th in the SE in AR13029 while the group in AR024 had reduced in size to a CV Axx.
Prominences around the limb of the Sun were quite active.
On the 6th only one single Axx remained in AR029 while an unconnected arch Prominence on the SE limb reached a height of 65,000km.
On the SW limb close to the equator I saw what I believe was a type B2 Flare. It was not confirmed. It started at 23.50hrs UT, Peaked at 23.55 & ended at 00.15 the following day. It had an X-ray class of B3.4
The solar disc was clear of Sunspots on the 7th & 8th June though on the 9th a Bxi group reappeared in AR13029.
On the NE limb an active Prominence reached a height of about 83,000km with some Surge activity.
On the 10th a Bxi group of spots appeared in AR13030 and close to it a arched Prominence reached a height of about 47,000km.
Activity on the Sun now remained very low.
Activity once again increased on the 12th with four Sunspot groups observed, a Eso (CV26) group in AR030, a single Axx spot in AR031, another in AR032 and another in AR033.
Prominences remained minimal.
No further observations were made until the 24th. On that day a Dsi group (28) was observed close to the NW limb.
Above it a very active prominence reached a height of approximately 56,000km & stretched across the limb for about 205,000km
No further observations were made until the 27th when a new Csi (CV12) was observed in AR13042.
A short lived type B1 Flare was seen in AR13040. It started at 23.45 UT, peaked at 23.55 & ended at 00.15 on the 28th. It had an X-ray class of B4.
Summing up, sunspot activity so far for solar cycle 25 in June 2022 has become less active but with Prominences & Filaments becoming stronger. Flares were observed on the 6th & 27th on my watch during June.
The most Sunspots seen on one day was 11 in 4 groups & the most groups seen on one day was on the 28th with 4 groups which included only 7 Sunspots.
11 daily observations were made for the month of June.
A total 14 areas of Plage and a total of 2 Flares were observed for the month.
The relevant sunspot number for the month was 20 and the average CV number was 15.5.
My forecast for the month of July is a further increase in Sunspot and Flare activity and an increase with stronger & brighter Prominences. (weather permitting)
