Tommi Ropponen, Ursa (Etelä-Suomi)

A quick description of a working day from the parking lot. In the air between the thin fog and the thicker clouds, I managed to shoot one 20 s video without the clouds passing in front of the sun.

Partial solar eclipse

10.6.2021 at 14.09 - 14.32 - Espoo (IV)
Tommi Ropponen, Ursa (Etelä-Suomi)

Partial eclipse photographed in Espoo. The vibration of the atmosphere was quite intense in the afternoon, so the quality of the images is not quite what it could have been in the event of an eclipse, for example in the morning. I photographed the hydrogen alpha first from the courtyard of the apartment building (Figures 1, 2, 4, and 5) and then quickly afterwards in white light (Fig. 3). A few different treatments are shown in the pictures. There was a bit of artifact left on the moon disk, but you have to watch if you could handle these files on a rainy day. AR2829 and AR2832 as active regio...

The first tests left in the image processing queue with the current setup. A quick test session in the morning left a trace like this.

The first tests left in the image processing queue with the current setup. The later afternoon time is reflected in the image quality, but I leave this here for documentation purposes.

Several halo forms

Tommi Ropponen, Ursa (Etelä-Suomi)

The spouse spotted the phenomenon outside and would go talk about it. Fast mobile camera images in dng format from the hand. Stack and fast processing without any halo processing skills in Photar. Someone who is knowledgeable could get something out of these, unlike the undersigned. After all, nothing miraculous appears here, but for the signatory, the first observation of this kind. There would probably have been the joy of a decent fisheye here, but there was no such thing available. The first 2 images are a bit distorted in Photar and the last image is an example of a single frame translate...

Tommi Ropponen, Ursa (Etelä-Suomi)

The encounter early in the morning seeing was actually great and comfortably visible on the reel active areas AR2018, AR2020 and AR2021. According to SpaceWeatherLive, the comma number was 47. This way, as the sun's activity rises, there will still be a lot to describe here as a summer vacation.

Tommi Ropponen, Ursa (Etelä-Suomi)

The sun photographed through the gauze, on the surface of which the active region AR2814 is visible. Visibility was poor when there was something thin cloud gauze in front of the puck all the time. I lived up to better hopes for this active area, but the weather was not favorable now. A little more detail could be excavated from the black and white image to be seen with the naked eye. Due to the weather, only 10% of the image stack could be stacked when the material was so weak. Generally, the corresponding stack contains 30-40% of the images.

Tommi Ropponen, Ursa (Etelä-Suomi)

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.

Tommi Ropponen, Ursa (Etelä-Suomi)

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.

Moon

26.3.2021 at 17.48 - Espoo (II)
Tommi Ropponen, Ursa (Etelä-Suomi)

The moon practically from the daytime sky. The clouds pushed on top, so if the picture was going to get it, it had to be used for taking well before sunset. The moon was not very high. This is reflected in the image quality, but the shooting project shouted this stage to be photographed as well, so it didn’t help. As a reference, a small raw image exported to jpg without any changes. Pretty much got to process this image and the quality doesn’t really end up dizzying.

Moon

Tommi Ropponen, Ursa (Etelä-Suomi)

This project also yields about 86% of the moon.

Sun

25.3.2021 at 14.00 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

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.

Moon

Tommi Ropponen, Ursa (Etelä-Suomi)

Seeing was quite matter-of-fact, somewhat better than the previous few days. Photographic optics of a crack in a balcony glass without monitoring. I would suspect that this is now starting to represent roughly the best quality that can now be described with my own tele-optics. I noticed that the one doesn't show up here in its native size, so I put a link here, behind which it can be zoomed to its full size: https://www.flickr.com/photos/130947324@N08/51068631751/

Moon

22.3.2021 at 20.30 - 21.00 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

Balcony glasses open and familiar for the job. In describing this, the moon was really high, but the weather was still worse than yesterday.

Tommi Ropponen, Ursa (Etelä-Suomi)

Balcony astronomy continues. Sadly, the 20-day image is now missing from the series due to the clouds.

Sun

Tommi Ropponen, Ursa (Etelä-Suomi)

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.

Moon

19.3.2021 at 19.45 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

This too was photographed from the balcony. It should be about 30% of the moon. The weather was worse than the day before and the atmosphere was quite restless.

Moon

18.3.2021 at 19.30 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

Quickly 22% of the moon photographed with telescope between the balcony glasses.

Sun

18.3.2021 at 15.10 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

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

Tommi Ropponen, Ursa (Etelä-Suomi)

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.
