[kstars] [Bug 497129] New: diameter of SUN is displayed wrongly
https://bugs.kde.org/show_bug.cgi?id=497129 Bug ID: 497129 Summary: diameter of SUN is displayed wrongly Classification: Applications Product: kstars Version: 3.7.3 Platform: Mint (Debian based) OS: Linux Status: REPORTED Severity: grave Priority: NOR Component: general Assignee: mutla...@ikarustech.com Reporter: ulli_kae...@posteo.de Target Milestone: --- Created attachment 176393 --> https://bugs.kde.org/attachment.cgi?id=176393&action=edit screenshot of the eclipse as seen from Barcelone, Catalunya Desktop Planetarium Build: 2024-11-23T20:19:59Z SUMMARY I tried to reproduce the total Solar eclipse of Aug. 12, 2026 as seen from Barcelona. I found out that kstars wrongly predicts the ecipse to be total from Barcelona which it isn't. STEPS TO REPRODUCE 1. set Geography to Barcelona and time to Feb 26, LT approx 21 hours 2. the Moon should almost cover the Sun as displayed on the star chart 3. measure apparent diameter of Sun and Moon OBSERVED RESULT The Moon's disk is plotted with the correct diameter (correct here means the diameter as given under details is the same as the one I measure with the cursor from the star chart) For the Sun, however, the details-box gives a diameter of 31.6' while I measure with the cursor from star chart ~29,1' i.e. 2.5 minutes of arc less. >From the screenshot it is obvious that the diameters don't match. As is the path of totality comes out way too wide. EXPECTED RESULT I would expect the Sun's diameter to be given properly. The above described bug gives a 'bad press' to the otherwise for me perfect program kstars!

https://bugs.kde.org/show_bug.cgi?id=497129 --- Comment #3 from Ulli --- Hi Everybody I know that you are probably working hard but I really want to COMPLAIN I just installed the latest version of kstars (3.7.7) and I noted that the error of the program, diameter of Sun displayed wrongly, has not been fixed. I don't know your priorities but in this context I want to explain my frustrations. I am trying to educate the general public about LINUX, open source etc. in general, but especially also about kstars. Moreover, living in Barcelona I try to explain everything about the Aug. 2026 total Solar eclipse to the general public. I would like to use kstars to show what will happen and it is frustrating that such a simple error has not been fixed. I understand that kstars is not meant to predict eclipses, but minimum courtesy would be that someone at least reacts to a well documented and analyzed error in the reporting system! cheers Ulli -- You are receiving this mail because: You are watching all bug changes.
