(meteorobs) June Lyrids, Xi-Draconids and possible "phi-Herculids"?
Hi all !
I was able to observe 1.22 h Teff this night, trying to monitor the
June Lyrids and Xi-Draconids. No member of both shower were seen. My
first meteor hit exactly the radiant in Lyra, but it was really to fast
(30°/s) to be a June Lyrid. Another meteor was a good candidate for the
Xi-Draconids; it had the good speed (3°/s), but it was a very short one,
that I think was too far from the radiant ( 20° ) to be a Xi-Draconid.
In fact, I was sending this mail because as I traced all my meteors back
this morning, I realized that four of them was coming from a same point
of the sky, very, very close from the star phi Herculis. Two of them had
very short path (including the meteor first thought as being a
Xi-Draconid), and slow motion ( 3 and 6 °/s) . The two others were more
far from the possible radiant and really faster.
I found that this possible radiant lied at the coordinates :
RA = 17h20' (260°)
D = +37°
The velocity of these meteors would be very high.
Has anyone ever heard of this possible radiant? Has anyone observed
meteors from this source? Have I saw an outburst of an unknown radiant ?
Thanks of advance for answering these questions. I'll try to monitor the
sky the next nights, if I'm not too tired...
Clear skies !
