(meteorobs) Information of GIA Obs.
Hi All,
I introduce some Giacobinids observation of Kazuhiro Osada.
He says that Giacobinid shower activity has already started in this year.
In fact, he detected its radiant.
The other hand, Ms. Mitsue Sakaguchi witnessed its characteristic
meteors on Oct. 1 and 4.
I'm interested in the maximum day of the Giacobinids in this year.
Clear skies. Takema,
