Dear meteor observers, MDC members

This is a brief report of possible new meteor shower observation (update of PMSR_20130408JP_1).

A compact and very shot time(only within 2h34min) 15 meteors concentration was observed.
7 orbits out of 15 were computed as hyperbolic. So this event can be the first and the last for the Earth.
We call this concentration  as "1uky" until official shower name is given by MDC.

Forum Event Log(UT+9h)
06:09 8/Apr Shimoda upload NN4 7-8 observation result to the SonotaCo Network Hub with a comment "It was not so clear sky"
07:40 8/Apr Inoue upload KN1 7-8 observation result with a comment "There were many meteors comes from east".
08:03 8/Apr SonotaCo upload TK1 7-8 observation result with a comment "It was very fine but transparency became a bit bad. Bright meteors appeared beyond my expectation for Japanese spring"
08:27 8/Apr Shimoda noticed the concentration using UO2 on 3 stations data, and opened a new forum topic for discussion of this event with a title "Emerging fast meteor shower outburst from south of Aquila 20140408".
10:51 8/Apr SonotaCo issued the first "Possible new Meteor Shower Report(PMSR_20140408JP_1) for 10 related persons in the world.
16:17 8/Apr SonotaCo decided the temporal name of this shower as "Jx_1uky" using 4D code that corresponds to 4chars of (sol, ra, dec,Vg).
12:38 9/Apr ts007 computes 13 shower meteor orbits from 11 station data uploaded.
10:xx 10/Apr Observed 1uky meteors became 15 according to the most of the single station data uploaded. SonotaCo make this brief report upon this.
