Bug Description
I am see conflicting information when I compare Heavens Above (HA) predictions to Stellarium. Specifically the following incident has multiple errors:
Location: 38.6089°N, 78.0561°W
Heavens Above (HA) predicts the following flare:
Flare Details
Date: 23 November 2016
Time: 18:39:02
Brightness: -8
Altitude: 45°
Azimuth: 34°
Satellite: Iridium 11
Distance to satellite: 1049 km
Angle off flare centre-line: 0.2°
Distance to flare centre: 3 km
Flare producing antenna: left
Sun altitude: -20.3°
Angular separation from Sun: 135.1°
However, I tried to simulate this in Stellarium and I get two other flares not predicted by HA:
Iridium 26 flare at 18:38:09 at magnitude -2.5
Iridium 20 flare at 18:39:02 at magnitude -7.2
And Iridium 11 is below the horizon at this time!
So why is the Iridium 11 info conflicting and are these other two flares real?

First, Stellarium do not related to Heavens Above website and we can't comment how accurate is predictions on that website. Second, are you updated the TLE for Iridiums? Third, for any software/website the criterion of accuracy can be only real phenomena - please report the errors in comparison with real sky.
