Version: 1.5.3 (using KDE 4.3.1) OS: Linux Today, 6th Oct 2009, "Whats Up Tonight" shows The moon as "Waning gibbous (77%)". If I right click on the moon in the star map and select "Details" it shows the illumination as 40%. Neither are correct. KStars 1.2.9 on KDE 3.5.10 shows "Waning gibbous (91%)" and current illumination 93% which I believe are correct as verified by www.heavens-above.com.
Wow. Thanks for finding this really embarrassing bug!
I find that the % illumination keeps varying randomly upon repeated opening of the Details dialog, when the clock is running at least. I wonder if Alexey had highlighted this earlier on the mailing list, so I'm putting him on copy.
SVN commit 1032026 by asimha: Fixing a bug with the calculation of illuminated fraction of the moon. The Phase was stored in degrees, but was multiplied by 180 / PI instead of PI / 180 while converting it into radians!
