- 9. The activity of the May Alpha Bootids in 2000.
- By Takema HASHIMOTO
- The enhanced activity of the May Alpha Bootids was observed during May 23 to 29, 2000 in Japan. The maximum activity occurred on May 24 with HR = 3, and the radiant is alpha = 212, delta = +17. The same shower appeared in 1970, 1998. As the radiant of this shower is near the predicted radiant of comet 73P/Schwassmann-Wachmann 3, it is possibly associated with comet 73P/Schwassmann-Wachmann 3.
