    PNAS-observations from
    Bram Dorreman
    Site 4160: 51.27931 N, 5.47683 E, 35 m (WGS84)
    
    General notes:
    The times reported in the hh:mm:ss.s column are the predicted culmination times.
    
    I'm still looking for a suitable shorthand for my notes.
    Some attempts:
    L in the comments column means "flaring".
    "bt" is the abbreviation for "between" and is placed between the
    concerning objects.
    maxmag = magnitude at brightest
    oo = other object (than the one I was following or searching)
    ! is the separator between azimuth value and altitude value (in degrees), like
    the + or - is between right ascension and declination values.
    
    T-P means Timed minus Predicted Time (format hhmmss.s)
    
    ref** means reference stars are
    
    Sometimes I report something like:
    123456 1234+56 123!45 then it means
    hhmmss hhmm dd aaa ee with
    hhmmss: time
    hhmm: right ascension
    dd: declination
    aaa: azimuth
    ee: altitude.
    
    Any useful suggestions for improvement of additions are welcome

    Specific notes:
    1) 07026A, 31698, TerraSX and 10030A, 36605, TandemX
       are a wonderful pair with a separation just
       large enough to see two objects.
       They showed a fast rise and fall in brightness rivalling alpha Lyrae
       with a golden glare
       Their Az/alt values near the point of maximum brightness are given
       together with the same values for the sun.
    2) While waiting for 07059A, 32376, Skymed 2 to flare (near alpha Lyr)
       I saw another object near Kochab (beta UMi) flaring.
       Guide 8 tells me that it was 10028D, fragment of the rocket that launched
       Picard, May be this is a cover or plume shield?
    3) Just a magnitude estiamtion for 10046A, 37162, FIA Radar 1.
