(meteorobs) 2004 Perseids in JAPAN (Visual)

[Hiroshi Ogawa]

Hello all,

I send you Perseid analysis in Japan provided by Mr.
Shigeo Uchiyama.

And I cannot participate in IMC 2004. I would like to
participate, but I have to work. So, I cannot go in this
year. However, I would like to participate in IMC 2005 or
2006. I am looking forward to seeing everyone !
