(meteorobs) June Bootids in JAPAN (Visual and Radio)
Hello all,
I send Japanese Bootids results by Visual(The Nippon Meteor Society)
and Radio(The International Project for Radio Meteor Observation).
======Overview of Japanese observed results (Radio and Visual) =======
Almost of Japanese Radio Observing stations monitored 7P/Pons-Winnecke
meteor shower 27th evening(UT). I am receiving many reports from each
observing stations. In these results, we could not seen and detect an
outburst activity cleary. On the other hand, some of stations reported
very week increase of meteor number around 19h(UT). But these are not
clear. Therefore, we are thinking "no outburst".
I am receiving and collecting observed data now. When I receive new
reports or comments, I will forward to everyone.
In Japanese visual observation, I do not receive report now. This is
because it was very bad weather last night. So, there is a few visual
reports now. In June, Japan is rainy season....
========== Radio reports in Japan ===============================
I received many radio reports from following observers (9sites).
-- Masayoshi UEDA, Kouji OHNISHI, Hirotoshi HARA, Ibaraki-NCT,
Univ.of Tsukuba[Hiroshi OGAWA], Toshihide MIYAKE,
Yasufumi YOSHIKAWA, Naoki MORIWAKI, Masaaki OGAWA --
And I received comment with observed data. So, I translate these
comments in English (please do not forward these comments)
[Masayoshi UEDA]------------------------------------(Osaka, Japan)
Around 19:30(UT) on 27th, Pons-Winneke showed outburst ??
Although the radiant elevation was around 7deg., meteor echo number
increased... How about other observing station ??
My graph is obtained from following. (Japanese page)

[Masaaki OGAWA]-------------------------------------(Kagawa, Japan)
I also caught increase of meteor echo. Especially, 19:43UT-19:50UT.
[Kouji OHNISHI]-------------------------------------(Nagano, Japan)
From 2loop antenna's result, I could not catch clear fluctuations.
[Toshihide MIYAKE]---------------------------------(Okayama, Japan)
At my observing site, I could not confirm a increase like outburst.
Although there was more meteor echo in 19:40-19:50UT than usual,
this is seen usual fluctuation range.
I show some of reports by Radio Meteor Observation as following.

=============
note:
--: lost counts because of high noise level or machine failure.
%: Hourly rate estimated by effective observation time less than 60 min.
NS: something noise
IF: Contamination due to radio noise or interference
Es: Contamination due to sporadic E opening
CW: Continuous Wave
JST =UT + 9 h
