    Here are my magnitude estimates of "flaring" geosats.
    I always used a 15 x 80 pair of binoculars.
    Column headings:
    cn = NORAD nr
    sn = international designator
    name
    longitude, postive east (Mike M does not like that ;-)
    azimuth
    altitude
    dates in month-day format.
    
    All identifications made by using program FINDSAT.
    All predictions afterwards made by using program HIGHFLY.
    Mostly I used the four star asterism at following location as reference:
    star A: 10 11.28 -07.32
    star B: 10 11.20 -07.04
    star C: 10 13.72 -07.38
    star D: 10 13.36 -07.00
    coordinates given by program PN.

    Thanks to Mike McCants for having his programs available for other amateurs.
    I was not always able to identify objects due to objects very close to each
    other.
    These objects are not mentioned.
