Re: (meteorobs) meteors from Hydra during the Leonids
Hi Jim,
About November Hydrid, we have been known it at least 40 years before.
We call the minor shower epsilon Hydrid in Japan. My investigation, its
activity period from Nov. 10 to Nov. 22, the velocity is rapid and the
radiat drift is as below.
Visual TV
R.A. = 131 + 1.1(Ls-240.3) R.A. = 128 + 1.0(Ls-236.0)
Dec. = +4 + 0.0(Ls-241.3) Dec. = +9 - 0.2(Ls-236.0)
This shower is not same as Sigma Hydrid. but, the maximum is not clear
(about middle of November.)
About this shower, I wrote it as follows.

Clear skies, Takema.
