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!
