Hi,
I enclose you
my observations made in mountain for the Perseids.
The Eridanids seems to be
of the meteors that come from one zone between the constellation of the Cetus
and the Eridano. They are some years that I observe to them and some years
behind are successful to photograph of one.
Perhaps also this year I have
photographed one, but I must develop the
negative ones to you. Someone of you
has observed meteors to come from that zone this year or in other years (video,
visual or photographically)?
