Sunspot (20230802) - ISS Transit rehearsal

10 days ago I could capture the Sun for the last time. Today I tried it despite a mostly cloud covered sky and thus many passing clouds or even totally obscured sky between my setup and the Sun. I felt urged to reassure my setup and preparation is solid and good enough for THE EVENT scheduled for tomorrow (20230803):

Solar ISS Transit with a comparably big ISS appearance at an angular size of 55.94″ (almost one arcminute!).

I used to look for ISS Transit in front of the Moon or the Sun for about two years. And I checked Transit Finder for almost a year now for any transit not too far from here and of course high enough in the sky, thus observable it above our mountains.

Tomorrow (20230803) is the day and these are[b] [/b]today's predicted parameters for tomorrow:

    Thu 2023-08-03, 14:23:47.27  •  Sun transit
ISS angular size:55.94″; distance:493.91 km
    azimuth: 208.2°; altitude:57.4°
    visibility path width: 4.92 km
    Transit duration:0.68 s
    transit chord length: 31.5′

Tip:GIF animation ot how it should look - mind the running seconds!

The ISS is rather close to the Earth at only 493 kms. Thus, the whole transit only lasts for 0.68s while being high up at 57.4°. My chances are 50:50

and of course I am so excited if the Sun is freely visible in a big enough deep blue cloud hole!

ISS

Pray for me, guys, I need some very fine experience!

All chances are always 50:50 - either you get the goal ... or not.

Title: ISS Transit Simulation

Description: To visualize the tomorrow's ISS solar transit (20230803-142347h CEST) not far from my place, I prepared this GIF animation with "stellarium", recorded by "vokoscreen", converted to GIF by"ffmpeg"..

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
