** Prediction: 
Long.: 121o 00' 00.0" E, Lat.: 23o 46' 18.0" N
PredTime:    15h 22m 34s

**** Successful observations:
Observer:    Chilong Lin
Place:       Taichung, Taiwan
Long.: 120o 39' 00" E, 24o 06' 48" N, Height: 68m (WGS84, MSL)
Method:      VCR, 10inch f=1016mm Schmidt-Newtonian, WATEC 120N
Time signal: WINDOWS, automatically calibrated through web
Result:      D 15h 22m 35.100s +/-0.033s
             R 15h 22m 41.033s +/-0.033s
Note: Observation was made from ~15h 20m 00s to 15h 25m 00s.
  Asteroid: Visible.  Approx. Limiting Mag.: ~14mag.
  Duration: 5.933s +/-0.033s(15fps) or 4.733s + 1.133s
  (the latter is 15h 22m 35.100-39.833s plus 15h 22m 39.900-41.033s;
  see the comment below).
  Sky Transparency: Good, Star Image Stability: Good.
  I used a Watec 120N video CCD @2X mode (15fps), an AN to USB converter,
  and a notebook with the software "UFOCapture" as a recorder.
  The light curve was measured with LiMovie.
  There was a probable reappearance at 15h 22m 39.833s with
  duration less than 1/15s. But the brightness reading did not go back
  to its complete value. If it were caused by a satellite, the size of
  the satellite should be >14.78km by assuming the speed of the shadow
  was 13.04km/sec.
  It was said that in 1980's, some observation doubted it as a binary.

  Asteroid: Visible.  Approx. Limiting Mag.: ~14mag.
  Duration: 5.797s +/-0.1s(5fps).
  Sky Transparency: Good, Star Image Stability: Good.
  Data were taken through an ASI-120mm @5fps and recorded onto a PC.
  This site did not see the reappearance observed by Lin at Lingo's site.
  However, the 5fps time resolution could be not enough for such a short
  reappearance..
