    1) Timings: 13.92 15.47 13.69 11.78 13.24
    2) Evolution in brightnessvariation: M=>A=>F; max mag. in SW.
    3) While following 09021B by naked eye I saw magn. +1 flashes at
       21:37:47 21:37:58 21:38:12 and 21:38:25 higher in the sky and
       shouted to record these on my voicerecorder.
    4) Maxima evolved from A to A with a small flash on top of it, making
       it easier to time.
    5) Typical brightness variation for a fairingpart: round maxima but with
       a short flash when at brightest.
