    Another warm night. After some cirrus in the evening it cleared at
    dusk. Saw several nice perseids. At midnight UT more cirrus.

    Toward the north regular pattern.

    Timings at different intervals: 10 9 8 7 6 5 6 7 8 9 10 flashes,
    then 6 x 10 flashes; 20 x 1 flash and 7 x 10 flashes.

    7.31 7.38 7.42 7.80 7.71 8.01 8.28 sec.
    Strange that the 1 flash timings are much longer than when counting
    in groups.

    4.89 5.26 3.70 4.33 3.24 3.90 4.17 4.73 4.14 sec.
    Not sure about number of flashes, due to small amplitude.
