    On the morning of August 14 at 02h51m20s UTC
    (+/- 5s) I observed from Saarbruecken-
    Bischmisheim, Germany (lat. 4912'52" N, 
    long. 0703'42" E, alt. 293) a bright satellite
    (mag 1-2) close to Gamma Peg at about
    R.A. 00h00m, decl. +15 (J2000.0). Less than
    half a minute later the satellite crossed
    through the constellation of Cepheus.
    Probably the same satellite (also at mag 1-2)
    was observed on the morning of August 20 at
    03h11m25s UTC (+/- 2s) close to Epsilon Cyg
    at about R.A. 20h34m, decl. +32.5 (J2000.0).
    At 03h12m24s UTC (+/- 2s) the satellite was
    halfway between Alpha Lyr (Vega) and Gamma Dra
    at about R.A. 18h19m, decl. +45.1 (J2000.0).
    I tried to identify this unknown satellite by
    using Guide 8, but very surprisingly I could
    not find any match. My object was included
    neither in ALL.TLE nor in CLASSFD.TLE.
    I entered the two positions that I obtained
    on August 20 into SatCal 11.0 (by Gerhard
    Holtkamp) and got the following result:
    Year of epoch: 2010
    Day of year. Fraction of day: 232.13292824
    Right Ascension (deg): 23.5203
    Arg. of Perigee (deg): 50.2951
    Mean anomaly (deg): 0.0000
    Eccentricity: 0.0000000
    Inclination (deg): 96.3993
    Perigee/Apogee height (km): 393.9369
    Mean motion (rev/day): 15.56749351
    My object is apparently in a sun-synchronous
    (probably eccentric) orbit and might be
    something like a KH-11. Do you have any idea
    what it might be?
