(meteorobs) Leonids in Japan : Preliminary results
Leonids 1999
Visual results in Japan (The Nippon Meteor Society).
ZHR has been computed with:
- gamma = 1.0 (correction of Radiant elevation)
- r = 2.0 (equal "IMO Shower Circular,LEONID Activity 1999")
- excluding:observations under unfavourable condition
(T<30m, Lm<4.0mag, Cl>0.4, RP-h<10deg)
- SD : standerd deviation of ZHR
- Err. : ZHR * 1/SQRT(#Leo)
