    It is possible to have flares from two antennas (far apart) but also
    from the solar panels, and those can occur close to an antenna flare.
    But the panels are controlled depending on Sun's "declination" above
    the orbit plane, and at this time of year I don't find any for your
    location (Rob Matson's IridFlar). Probably the panels are pointed
    nearly 90 degrees from the orbit plane, close to the Sun near Marathon
    period.
    
    And Iridiums move S-N or N-S essentially !
