    On 08-21, a near-zenithal pass, only a normal flare was seen.
    I (thought I) missed it at 30 el., so I looked in binoculars
    at eps Lyr, near 50 deg., when I saw the end of a long flare
    before it entered the FOV. It was bright (+3-4) unusually far N.
    
    On 08-23 it was mostly cloudy (as 08-22) but while some gaps
    appeared I saw a strange sight. At about 20:02 UTC I noticed
    a "star" mag. +1 or so, at appr. RA 19:35, dec.+65, which looked
    fuzzy. I thought it was a bright flare, shining through clouds,
    but it remained for 15 minutes and appeared steady. At 20:08:29
    a +3 satellite passed within 3 degrees. The patch was oval,
    about 0.2 x 0.1 degrees, pointing N-S, near zenith. It barely
    increased its size when clouds passed, and not its brightness?!
    At 20:17, it faded to invisibility in about 30 seconds.
    
    I have seen searchlight patches on clouds, but they were larger,
    and moved/disappeared as clouds passed. I have also seen laser
    beams, but the beam has been visible, and again the end point
    has been mobile. I live 12 km from a civilian airfield, 25 from
    disused Air Force base.
