    In the video the probe reach the apparent greater magnitude at 17:50:31
    (0:26 seconds of video), when it crosses at right of the star Beta Ophiuchi
    (mag ~2.7).
    
    If we compare the mag of the probe at this moment it looks like reach a
    magnitude a little greater than Gamma Ophiuchi (mag 3.75 - the brigtest
    star at left of Beta Ophiuchi), but lower than Beta.
    
    So the brightness of the probe is around of that of the prediction given by
    Heaven's Above to the magnitude for the probe in this passage in Leiden: 3.0
