[vsnet-chat 353] supercycle of RZ LMi

[Taichi Kato <tkato>]

  Owing to the efforts of observers, particularly to Gary Poyner, the
superoutburst times of RZ LMi have been followed quite well this season.

Brightest observation of each superoutburst:

                                   JD-2400000
  961108.119   139  (G. Poyner)     50395.619
  961214.025   139  (T. Vanmunster) 50431.525
  970103.980   140  (L. T. Jensen)  50452.480
  970126.940   142  (G. Poyner)     50475.440
  970213.835   142  (G. Poyner)     50493.335
  970304.835   140  (L. T. Jensen)  50513.335
  970324.855   139  (G. Poyner)     50532.355
  970415.889   140  (G. Poyner)     50554.389
  970506.894   139  (G. Poyner)     50575.394
  970523.919   139  (G. Poyner)     50592.419

  By applying least-squares fit to these data, we obtain

  Max.JD = 2450393.8 + 19.97 E

  and residuals

 JD-2400000   E   O-C
  50395.619   0   1.8
  50431.525   2  -2.2
  50452.480   3  -1.2
  50475.440   4   1.8
  50493.335   5  -0.3
  50513.335   6  -0.3
  50532.355   7  -1.2
  50554.389   8   0.8
  50575.394   9   1.9
  50592.419  10  -1.1

  The derived supercycle length of P=19.97 day is about 1 day longer than
that by Robertson et al. (1995), which was determined using the 1992
Sep. - 1995 Jan. RoboScope data.
