    NOTES:
    ------
    (1) Four IGS 8 objects should have been visible; the passes of 99048,
        99049 and 99050 were close to what was predicted. Object 99051 was
        not seen.
    (2) Unknown 99056 correlates with both SAR Lupe 1 [29658/06060A] and
        SAR Lupe 4 [32750/08014A]. This circular orbit estimate should be
        reasonable to recover it.

    (3) Unknown 99057 was seen during the IGS 8 planar search and matches
        the orbital plane of the IGS 8 launch. It may be the 99051 object,
        but I could not get a satisfactory orbit describing these and
        previous observations.
    (4) I reobserved Scott Tilley's 99139 unknown from April 23rd. It was
        quite variably with lots of short flashes, one of which must've
        been magnitude zero. It is unclear what this is. It seems to
        correlate with IGS R2 [30586/07005A] but does not match previous
        observations that were attributed to it recently (see below).
        The following orbit describes the observations reasonably well:
    1 99139U 13613A   13117.04537333  .00000000  00000-0  50000-4 0    04
    2 99139  97.9661 252.6116 0010000 221.5352 199.0952 15.41913623    05
    (5) Surprisingly, IGS R2 [30586/07005A], IGS 6A [37813/11050A] and IGS
        6A r [37814/11050B] were not seen even though the passes were
        favourable. I wonder if the IGS constellation has been
        reconfigured with the arrival of IGS 8, leading to some objects
        that were recently recovered being misidentified.
