After a month’s break, I finally got to shoot the brightest comet just below the mag 9 limit. It is estimated that towards the end of the year, the comet should still brighten by its magnitude, but unfortunately it will not be visible to the naked eye. More information here .

A handsome anvil cloud appeared eastward early this morning. The temperature was pleasant (compared to noon) +17 degrees humid. The summer morning feeling was really in place. The mist raft above ground level and the shadows cast by thunder clouds into the hazy air added to the atmosphere.

Checking the night sky at half past one, at first there seemed to be nothing, but yes there were rays of twilight again. I watched for a moment, then back to sleep.

One slightly larger dot and several small spots appeared in the sun today.

We got on a long night shooting trip. Sunsets were described and post-sunset color reflections in lakes and bays. Afterwards, I only realized that there were very weak illuminating night clouds. The colors caught my attention when shooting. It was a hot, beautiful night.

In the beginning, the area covered by the night clouds was indeed small, but it expanded and then moved all the time, still remaining strictly to the north. Figure 1 was taken at 1:20 a.m. when the area was at its widest. Figure 2 is a timelapse of approximately 90 frames over the entire observation period. Edit: corrected observation time (00.40 instead of 00.14)

Sunspot 3038. Sunny weather, of course, favors description but heat usually means poor seeing. Using a meter, I found a place on the plot where seeing was good. Steady wind and water surface a few meters away. I reduced the imaging area (ROI) of the sensor, got a faster shooting speed, and in half a minute I got a couple thousand images of which I stacked a few hundred. With this technique, I got clearly more details visible. My goal is to take a high resolution picture of the whole sun but making a mosaic is so challenging that I try to learn how to get more out of the bigger sensor. Lunt 80 ...

In April, I spotted a TESS telescope exoplanet from candidate TOI 4437.01 In the light curve, my partial observation of the output I got grabbed. I spotted the subject for four hours. In total, the duration of the event is 8–12 h. There were more observers, so it is hoped that we were able to detect the overrun as a whole. This is still made into a combined light curve and it is hoped that we were able to confirm that this exoplanet is real. According to preliminary data, this planet is the size of Jupiter.

Here in the sky it has been quiet. I saw a heavier rainbow from the car the day before, but it had time to disappear before a stop was found. I quickly photographed this from the stairs on my cell phone so I wouldn’t have time to escape.

The crescent moon rose into the clear sky and was still able to separate the planet Venus before sunrise with the naked eye.

The dim sunrise was visible even before sunrise, and the left side sun was only dim, but these too had to be recovered.

I woke up after two and went to check if anything was visible in the sky, there were clear night clouds heading north.

At half past one, the night first looked like a version of the previous two nights. There is a hint in the second picture 0:32 but not enough for identification. In the northern triangle 0:46, the observation was visually certain. From there it then expanded. The first image I took 0:54 (illustration-type editing is not a scientific record corresponding to visual observation). Vito's North 2:14 is at the end of the show. I chose 1/8 for the extent, although 1/16 of the entire visible sky area would be more accurate, but the area was not very small.

Alarm type, something in the north. Considering the light, quite moderately visible. Quick rap on a cell phone.

There are now enough twilight rays for the third night in a row. The mind would still go to the terrain to look at the other party as well, but now I have to sleep in between and settle for this one picture I took from my balcony.

Today, the memory puts the settings in a better pattern than yesterday. So here are the 43-minute animations shot in 50 screens. Also, as still images, a few pictures of the active area at the edge of the sun, which I also shot yesterday. Link to the full-size animation here: https://astrob.in/epaun3/0/ (may take some time to load because I combined all the different processing into the animation at once).

Rays of Twilight, Ilona for the second night in a row, though not as handsome as the night before. The same image as in my night cloud observation, but treated again and differently, Veikko Mäkelän made those rays stand out better than I got by processing the image myself.

Over the early summer, I built Sol’Ex spectral heliography according to Christian Buil’s instructions . The device can capture the sun at any wavelength of visible light. Attached is an image of the chromosphere of the sun this morning in the light of the H-alpha wavelength (656 nanometers).
