Dear all,
I am Mikiya Sato.
I could also watch enhanced Eta Aquarids, yesterday.
Many bright meteors of ETA were observed even in Japan.
Our results of visual observation were as follows.
May 6, 2013
Time (UT) S.Long Teff F Lm ETA HR ZHR(r=2.4) Obs.
1655-1725 46.15 0.50 1.0 5.90 5 10 94 T. Sato
1725-1755 46.17 0.50 1.0 5.90 10 20 120 M. Sato
1800-1830 46.20 0.50 1.0 5.90 15 30 129 T. Sato
1830-1850 46.21 0.33 1.0 5.70 7 21 90 M. Sato
*Location : 138d44.8'E 35d26.5'N 1200m Yamanashi, Japan.
>From IMO web, it seems that two peaks of ETA were observed.
The first peak time was about 3h on May 6.
Probably, this was formed by -910 trail.
Similarly, the 2nd peak about 15h was caused by -1197 trail.
However, these two peaks might be continuous.
And, the outburst lasted about 2 days or more.
This may mean that distribution of dust had spread
because two or more kind of dust trails approached.
I have to examine it in more detail in the future.
Thank you very much to all observers!
Best regards,
Mikiya Sato
