February 7th, 8.05am.

Region 2939 still features the largest spot along with a four small spots. Also in the south is New Region 2942, which is close to the Western Limb and only has a few small spots.

In the Northern-Central area, Region 2940 is still prominent with 2 medium and an array of small/tiny sized spots.

Region 2941 has a pair of medium sized spots surrounded by a common umbra, which makes it look like a large spot. Also visible is another, more widely separated pair of medium spots plus a number of small spots.


I have edited this on February 8th, as I had an old-timer's lapse and mixed-up what was north and what was south.

Thanks for your ongoing updates.

We have been much luckier in Melbourne the last few days. We have been waking up to sunshine.

Region 2940 has an interesting swarm of fine spots surrounding three medium-sized spots. I used a Green (56) filter, which allowed this feature to appear darker and be in good contrast with the Solar Disc.

Northern Region 2941, although interesting, appears similar to yesterday.

In the South West, a lone spot in Region 2942 is about to cross the Limb. Region 2939 still features a very-large spot with nearby minor spots.

There is some Faculae visible near the South Eastern Limb.

February 9th, 8.05am.

Northern Region 2941 has developed into a chain of six spots, with large spots anchoring both ends. The other northern region, 2940 has lost its swarm of fine spots and now consists of a medium and a few small-sized spots. Interestingly, faculae is visible. I am surprised to see this as it seemed a little too far from the Limb for this to be seen.

Southern Region 2939 still boasts the largest spot, along with a few small spots.

New Region 2943 has appeared near the South-Eastern Limb. It has a small and three tiny spots. Yesterday, only faculae was visible, whereas today, I did not see any Faculae.

February 10th, 7.50am.

Three Regions visible on the Sun today with Southern Region 2939 still having the largest spot. The SDO image on Space Weather also shows R2943 in the South, but I failed to notice it.

Northern Region 2941 continues to show change each day. Most of the spots have decreased in size except for one (second from the end) which has grown. Region 2940 has begun its approach to the Western Limb. It consists mainly of small spots that are surrounded by lots of Faculae.

The large spot in Southern Region 2939 is now close to the Limb. A new Region, 2944 has been named close to the South-Western Limb. It has one small spot and Faculae.

I would have thought that this newly named Region was too close to Region 2939 to be deserving of a separate name, especially since I can see a large stream of Faculae connecting the two Regions without any interruption.

Region 2940, also with Faculae is about to cross the North-Western Limb.

The chain of spots between two moderately sized spots in Region 2941 continue to shrink in size, including the one the had yesterday increased in size.

Northern Region 2941 continues to feature; two, well spaced, moderately-sized spots. There are still some small spots between them, but it has stopped giving the appearance of being a chain of spots.

There is a small amount of Faculae close to the North-Eastern Limb, but no spots were visible.

The large spot in Region 2939 now looks meek, as it is extremely close to the South-Western Limb.

New Region 2945 has only a few, scattered, small spots and is located in the South-Western Quarter.

Another new Region, 2946 has appeared close to the South-Eastern Limb. It has a moderate and a small spot that both seem to be surrounded by a common Faculae.

There are three Region visible today, R2941 in the north, R2945 & 46 in the south.

Region 2941 still has two medium sized spots, with the eastern spot being accompanied by eight small/tiny spots.

Region 2945 with only a few small/tiny spots is approaching the South-Western Limb.

Region 2946 is still close to the South-Eastern Limb, so can not yet be seen in all it glory. It has one medium/large spot with umbra and two small spots nearby.

Activity is a bit mellow today with South-Western Region 2945 gaining Faculae, but losing spots as it approaches the Western Limb. I could barely see two very tiny spots.

Northern Region 2941 bucks the 'mellow' trend. It is approaching the Western Limb. The Region continues to show change from day to day. It now looks like four medium sized spots in a row, however, the inner two spots are close doubles when viewed closely. The activity to now has all be in the 'chain of spots', but now a small spot has appeared located at a right angle well south off the chain.

Region 2946 in the South East now boasts the largest sunspot. It has a few tiny spots nearby.

Northern Region 2941 is losing its luster as it approaches the Western Limb. The spot at right angles has been joined by another small spot, and to my surprise, it has been designated as Region 2747.

Region 2946 still has the largest spot visible today plus a nearby, small spot.

New Region 2948 has appeared in the South East near the Limb. It has a medium spot and three small spots in an arc.

Two spots have appeared in the central region in the South. They are a medium and a small/medium sized spots. This new Region is yet to be named.

Some distance from these are another two, very tiny spots. I am interested to see if they develop or just as quickly disappear without being named.

There are six Regions visible today. Only four of these Regions are named.

Region 2941 straddles the North-Western Limb with only the last two spots being visible.

There is a new, unnamed Region in the Central-Northern area, which has a small spot and some tiny spots. It was difficult to see.

There is a small spot and faculae in another new, unnamed Region that is very close to the North-Eastern Limb.

Region 2943 is new to me, but the number is old. This number previously appeared against a grouping that I could not find on February 10th and its number disappeared from Space Weather until today. It has two small and a number of tiny spots.

Central Region 2946 is beginning to look odd because of its location close to the Sun's equatorial zone. Regions are normally in Northern or Southern belts. Its large spot has downsized to be a medium spot, which has two nearby spots.

South-Eastern Region 2948 has developed significantly overnight and now has two medium sized spots and numerous small spots.

February 18th, 7.40am.

Region 2948 in the Southern-Central area has two close, small/medium sized spots, as well as a trial of small spots heading off to the East.

There is a small, unnamed spot, very close to the South-Eastern Limb. (Now named Region 2952- updated at 8.30am)

Region 2950 has a small spot and is located in from the North-Western Limb. Faculae is also visible near that Limb.

On the Space Weather SDO Image, there are three other Regions noted with faint spots. However, they must have faded further because I did not see any of those. (Regions 2946, 49 &51)


Update, 8.30am:

I had a further attempt at finding the missing Regions with the Sun higher in the sky and less cloud interfering.

New Region 2951 consists of one small and three tiny spots and is located in the South.

New Region 2949 has three, very tiny, difficult-to-see spots. It is in the North West.

I could still not see Region 2946.

February 19th, 8.50am.

There is a large spot in Region 2948 and three tiny spots. It is in the Southern-Central area.

Region 2952 near the South-Eastern Limb has only one small spot.

There are two small spots near the North-Eastern Limb that are yet to be named.

Space Weather shows Region 2950 with small spots, a little further west than the above two spots, but I could not see them.

Most people having a quick look at the Sun today will probably only see the large spot in Region 2948. The other spots are small, somewhat lonely and difficult to find.

It is a relatively quiet Sun today.

Southern Region 2948 has a medium and a tiny spot. South-Eastern Region 2952 has just one small spot.

Newly named, North-Eastern Region 2953 has just three tiny spots.

Region 2646 is shown on Space Weather, but I found nothing in that area.

February 21st, 8.00am.

New Region 2954 has appeared next to the North-Eastern Limb with a medium sized spot and umbra.

Northern Region 2953 has developed two sets of 'twin' spots and now has six, tiny spots in total.

South-Eastern Region 2952 still has only one, small spot.

South-Western Region 2948 has two, close, small spots. Yesterday, I described this as a medium spot, so it has split (I deduce). There is a third, tiny spot nearby.

February 22nd, 8.00am

New Region 2955 has a medium sized spot that is distorted into a long streak, as it is very close to the North-Eastern Limb.

Region 2954 is nearby, having appeared past the Limb a day earlier. With magnification (50x), I could see the 'Wilson effect' on the umbra of this medium-sized spot. This is when the umbra is smaller on the side closest to the Sun's Centre, compared with the umbra closest to the Limb. My understanding is that spot & umbra are depressions in the Photosphere and thus the umbra is viewed at different angles by observers.

I also looked for the Wilson effect in R2955, but could not see it.

In the Northern-Central area, Region 2953 is a collection of one small, and five tiny spots.

Southern Region 2952 still has just the one small spot.

February 23rd, 8.15am.

Regions 2954 & 2955 both have a large spot with umbra. Both spots look larger and darker today, which I assume is mainly because they are a further from the Eastern Limb. Both spots show the 'Wilson Effect" today.

The lone spot in R2954 is showing signs of dividing into two separate spots. The spot in R2955 has some very tiny spots nearby.

Region 2953 is a line of some six spots. Today, the small spot looks a little darker and more easy to see. The other five spots are tiny.

The large spot in Region 2954 has more internal structure today. It looked like three long spots, close together, lying in parallel with each other. I could again see the Wilson Effect.

The other large spot in Region 2955 also showed hints of structure. However, when I increased the magnification, I had problems with floaters within my eye. Nevertheless, the Wilson Effect was again observed.

Region 2953 is difficult to see. I only saw three tiny spots.

February 25th, 5.55pm.

The large spots in Regions 2954 & 2955 appeared like "Gemini" twins against a boiling Sun. That's all I could see, but according to the SDO image, that is all there is to see.

It has been cloudy and raining most of the day here, so when I saw some late afternoon sunshine, I tried my luck. As indicated, the seeing was terrible.
