The sun 31.5. and 5/27/2016 Slightly different image processing and colors as well as composite. The protuts were quite spectacular yesterday and this red section had to be made from yesterday's (May 31) material.

Yesterday's roar on the sun's surface. Unfortunately, during the shooting session, the sun was always covered in a thin cloudless cloud, but I wanted to get this gust to recover even if the quality is not the best possible. In the second image, the ground is served on a rough scale (the image is a free-use image from Nassa’s Apollo era, so I dared to add it here).

Testing with Quark and the acronym. Clouds came and went, seeing threw. Not in any way good weather yes except for individual boxes. Here, however, stuff is combined from a couple of squares. Maybe this thing could be summed up so that I don’t mean to get a cloudless sky this summer at all, so that I would sometimes have time to shoot more.

Mosaic practice. There was a thin cloud in the sky all the time, which softened some of the sub-squares of the mosaic. There are not very many spots in the sun at the moment. Better image processors would probably have gotten a couple of gradients out, but I myself gave up on this.

After breakfast, I realized that the sky has been properly clear for a long time. A quick glance at Nasa’s space weather app revealed that really nice protuts are visible on the surface of the sun. Kamat bundle and field. There was a thin cloud in the sky during the shooting, but when I grabbed 5 videos, one seemed to be more successful than the others. However, the seeing was surprisingly good at the moments when the clouds completely disappeared from the sun. The weather was great and especially warm for September. This may be the last sunshine this season. Fortunately, there was publishable...

Testing the new Quark when the previous one went under warranty due to uneven image area. The goal was to do tests with all of Quark’s settings to see what comes off the best image. As it was not completely cloudless in Espoo, we sometimes had to wait for the clouds to fade and in the end the battery ran out and the monitoring stand turned off and I didn't have time to go through all the settings. So sometimes you have to keep going. Probably the wisest thing to do would be to stay close to the mains, so there would be no need to leave the field a second time with your neck crooked towards...

The "test runs" continue and the sun is very dull. However, something small can be found on the surface as well as in terms of prototypes. What’s annoying with this warranty-exchanged Quark is that this new protut doesn’t seem to show up properly without their separate exposure. The former was unfortunately a better closet in this respect. I wish I could hope for even a few spots on the surface of the sun now, so that shooting would be more fun. The weather was good, really great, and in addition to the filming, I had to chat with probably ten passers-by and show on screen what a live image of...

Tommi Ropponen, Ursa (Etelä-Suomi)

There were 2 spots in the sun, so something small is happening after all. At the time of filming, a thin cloud of gauze was constantly sailing past the sun, so transparency was not best. Seeing, on the other hand, seemed reasonable. A few protests visible here and there, but no big flare. Warm enough when shooting, which is nice after the winter frosts. Again, there seemed to be interested enough, so the screen of the laptop became a play on the surface of the sun for a few passers-by.

Tommi Ropponen, Ursa (Etelä-Suomi)

The sun seemed to be a very active area that I tried to describe through thin clouds. In the animation, this is reflected in an unfortunate change in brightness. Seeing was worse than the last time, sometimes the picture was "just a whiff". The animations have 5 frames in each and the animation shows a period of 57 min.

Tommi Ropponen, Ursa (Etelä-Suomi)

The goal was to have a longer shooting session when the weather was right. I filmed the interval 12:20 - 14:33 until the batteries started to run low on batteries. There was that one spot in the sun, but nothing really happened in that couple of hours. The protut, on the other hand, were quite comfortable. The still image is stacked from a video started at 2:33 pm and features the earth approximately on a scale (the image of the earth is free-to-use images from Nassa’s Apollo era). The animation, on the other hand, consists of the entire time slot and contains 17 separate frames that are loope...

Tommi Ropponen, Ursa (Etelä-Suomi)

Yesterday it was cloudy in Espoo and the filming was not successful, but this morning the weather was cloudless. Seeing was also quite good, which can be seen in the pictures. Shortly before 1 p.m., the weather began to weaken and seeing deteriorated and eventually clouds sailed on. I have made it a habit, whenever possible, to be filming as early as possible, because the weather in the morning and in the morning often seems to be clearly better in the afternoon and evening. The pictures show the active area 2665, which was nice to include in the pictures, even though I went hunting for the pr...

First picture: Sun in CaK light in the afternoon 16.4. In my opinion, a rather large comma 2529 is visible, which was somewhere also called a heart commotion unofficially because of its shape. This has been described using a 1.25 "CaK filter with a bandwidth of about 8 nm. Therefore, the resolution is not in the same range as in dedicated CaK devices. Last three pictures: I ended up compiling a composite from the 2016 and 2017 Sun Photographs. The latter three images are thus collages in the H-alpha and CaK wavelength ranges. The blue portion in the composite is part of the first image of this...

For the first time, I was able to test teleoptics in solar imaging. When I didn’t have time to exercise for a longer period of time, I used to visit my actual telescope imaging equipment and switched to random visual viewing. But when shooting doesn’t stop, then from now on the sun will be shot without any tracking pads, computers, etc. This setup will carry out in 2 minutes and in shooting condition it will be 1 min after that. I could almost say that compared to my heavier previous fleet, this will get 80% of the result with 10% effort. Even if there was a comma still visible. After all, thi...

AR2806 and AR2807 photographed in the morning. The weather was quite good, but shooting over the roofs of houses is not the best option in direct sunlight. Nice spring day overall. I have also become lazy. I focused with autofocus on the surface of the sun and then locked the focus on it. This is but easy nowadays: D

The sun quickly captured in the morning. Apparently the AR2806 is shown in the picture and something else smaller there is on the other side. Two images with a slightly different treatment and a white sphere to mark approximately the size of the Earth relative to the Sun.

The AR2810 is currently visible on the disc and the tiata contains two separate dots.

A quick shot in the morning before the clouds covered the sky. There seemed to be little fog in the sky in the air in front of the sun. The clouds arrived shortly after filming and less than an hour after filming began, the sky was in full cloud cover. There were hardly any spots in the sun, although spaceweatherlive.com showed that the AR2810 should be visible on the disc. Some active area in the image is clearly shown on the left side.

A quick glance at the sun during the working day. A few active areas were visible there (could these now be from their AR2811 and 2812 designs?). Hopefully this trend will continue, so there will be more to spend the summer on that sun disk as well.

I leave this in the archive: At the time of shooting, the disc was virtually dotted. There is almost nothing to bring in the white light. H-alpha, on the other hand, would have offered whatever.

A quick glance in the direction of the sun on Sunday morning did not produce very ecstatic views in the white light. The active area of the AR2814 is visible on the dial, but the dots in it are really small.
