Object set/rise info is not refreshed when atmosphere is toggled

[kajaji]

Expected Behaviour

Rise/Set info change according to atmosphere on/off

Actual Behaviour

when turning atmosphere on or off the info of rise/set remains the same

Steps to reproduce

toggle atmosphere on and off while displaying for example sun set time

System

• Stellarium version: <25.4>
• Operating system: <windows 11>
• Graphics Card: <Manufacturer (likely Intel, NVidia, AMD?), Model (HD, Geforce, Radeon..., with model number), driver version?>
  This is a script with the results:
  //Test object info across status change

LandscapeMgr.setFlagAtmosphere(false);
var sunInfor = core.getObjectInfo("Sun");
core.wait(0.5);
var sunSetDecHrs = sunInfor["set-dhr"];
core.debug(sunSetDecHrs),
core.wait(5.5);

LandscapeMgr.setFlagAtmosphere(true);
var sunInfor = core.getObjectInfo("Sun");
var sunSetDecHrs = sunInfor["set-dhr"];
core.debug(sunSetDecHrs);
Result:
Starting script at Mon Mar 2 23:08:41 2026
17.89
17.89
Script finished at Mon Mar 2 23:08:47 2026

You will not find rising times without atmosphere in any almanac. Until now this is intended behaviour.

This is not a bug! This is a feature...

No problem. I encountered this while testing a script with atmosphere status changed, but stellarium will give different rts results according to atmosphere status, if I select the sun, display rts info, change the atmosphere, select another object, and then reselect the sun, the rts info will change.

Hmm, OK, this sounds like inconsistency. May be even interesting for some applications.

Hello @kajaji!

Thank you for suggesting this enhancement.

[kajaji]

There is another inconsistency with atmosphere off:
core.getObjectInfo("Sun") ["set-dhr"] result is different than core.getRTS("Sun") ["set-dhr"] .

when atmosphere on both have the same value.

Result of a script (see script code at the end):

time stamp: 2026-03-14T14:34:59

1. Atmosphere off:
   1.1 Result from core.getObjectInfo:
   decimal hours: 17.91222222222222
   HMS calculated from decimal hours: 17:54:44

1.2 Result from core.RTS:
HhMm: 17h59m
decimal hours: 17.983888888888888

2. Atmosphere on:
   2.1 Result from core.getObjectInfo:
   decimal hours: 18.025277777777777
   HMS calculated from decimal hours: 18:01:31

2.2 Result from core.RTS:
HhMm: 18h02m
decimal hours: 18.025277777777777

script:

//Test object info across status change
// Convert decimal hours → "hh:mm:ss" with carry handling
function decHoursToHMS(decHours) {
var hours = Math.floor(decHours);
var minutes = Math.floor((decHours - hours) * 60);
var seconds = Math.round((((decHours - hours) * 60) - minutes) * 60);

// Normalize seconds
if (seconds === 60) {
    seconds = 0;
    minutes += 1;
}

// Normalize minutes
if (minutes === 60) {
    minutes = 0;
    hours += 1;
}

var hh = hours.toString().padStart(2, "0");
