    Splendid night, nice view of the Milky Way, saw several meteorids.
    Some had a glowing trail that lasted several seconds. Radiant seemed
    to be around Lyra, Cygnus.
    Made obs in the evening in between two passes of 2000- 6 B, got
    some hours sleep and started in the morning at 01:20 UT to finish
    with Superbird A at 03:25 UT when it was becoming to bright to
    observe further.

    Is going up steadily, seems to have had an accelarion in early April, 
    when it got down from 18 sec to ?? When observing it again Jun 2nd
    I timed it at  7.1 sec. Or is it just that the sm were hardly visible?

    Now period gets longer, it seems that period is in fact the average
    of two periods; one around 8 sec, the other around 9 seconds.
