Prediction of meteor shower radiant associated with Comet 73P/Schwassmann-Wachmann 3

It is very paid attention whether the meteor shower appears associated with Comet 73P/Schwassmann-Wachmann 3
returned in this year. I think that a little meteor shower activity might seen on around May 22
when the distance between orbital arc of 73P and the Earth become minimum.
I want everybody to observe the meteor shower whether appear from the late in May to the early in June.

Table 1. Prediction of meteor shower radiant associated with Comet 73P/Schwassmann-Wachmann 3 (2006-C orbit).
The predicted radiants are calculated by the q-adjustment method (Hasegawa,1990)
by using the orbital element of main component of Comet 73P nuclear C in 2006 from MPC48382.
The predicted radiants position is much the same as the results of the calculation
by the orbital element at each return in 1979, 1990, 1995, 2001 and 2006 nuclear B.
