(meteorobs) Ursids in Japan : visual observation results -Update-
Ursids 2000 prompt report -Update-
Visual results in Japan (The Nippon Meteor Society).
ZHR has been computed with:
- gamma = 1.0 (correction of Radiant elevation)
- r = 2.5 (equal "IMO Shower Circular")
- excluding:observations under unfavourable condition
(T<30m, Lm<4.5mag, Cl>0.4, RP-h<10deg)
- Err. : ZHR * 1/SQRT(#URS)
r(population index) number changed. (3.0 -> 2.5)
