Strange behavior during solar eclipse

[StarFlea]

Hello folks!

Experiments with the solar eclipse on July 22, 1990 resulted in some strange displays, which I have documented in the screenshots below.

I wanted to find out by experimenting when and where the eclipse could be seen. To do this, I fixed the sun in view and opened the settings for date/time and location.
For example, when I gradually changed the latitude values, the sun suddenly came to be in front of the moon:

In another experiment, I gradually changed the time as the moon moved away from the sun, but the marked lunar landscapes remained with the sun:

Hello

For both issues I completely deactivated the atmosphere and the ground and was able to reproduce both again...

Would you check the behavior when Stellarium running with —low-graphics option?

[StarFlea]

Yes, with this option the phemoma also occurs:

Here's the procedure:

1. Select and center the sun
2. Set the date/time, re-center the sun if necessary
3. Hide atmosphere and ground
4. Open location
5. Zoom in to the Sun & Moon
6. Increase / decrease latitude until the moon moves away from the sun's disk: The moon-formation labels remain in place (maybe just their position needs to be updated when the location on Earth changes?)

I could no longer quickly reproduce the behavior of the sun being in front of the moon...

[StarFlea]

Ahh, the behaviour only seems to occur, if time rate is paused..

I can finally reproduce it. I had seen this earlier, but thought it was solved. This case is pretty hard to understand. :-(

[gzotti]

I also cannot reproduce Sun in front of Moon. However, the labels hopefully are now where they should be.

Hello @StarFlea!

Please check the fresh version (development snapshot) of Stellarium:

[StarFlea]

OK, now the formation-labels are always with the moon...

But as I tested the fix, the sun comes in front of the moon again:

I wonder what happened.

All I can say is that I first experimented with the location coordinates and then changed the time by the minute.
I then switched to my Firefox browser window and when I came back to the Stellarium window, the sun covered the moon...

I'm confused...

[StarFlea]

And now, when i returned to the browser and back to Stellarium, the moon is in front of the sun again...

Strange!

[gzotti]

Aw, yes. Sometimes! Confirmed "strange". :-( I saw it now, one click elsewhere only, and it fixed on the next click.

Re "Sun covers Moon": There is one experimental feature to be configured in the second skylight configure button: "Draw Sun after atmosphere (or similar)". When I did this (for an exhibition), I apparently did not think about eclipses. Make sure you have disabled this option. In any case, when the sun is drawn after atmosphere, it properly covers the Lunar crater labels.

[StarFlea]

Sorry, I can't find this option (or similar)...
But by the way: In this case atmosphere and horizon are disabled...
