(meteorobs) Possible "Delta Virginids" ?



Last night, I went to Dillingham airfield on Oahu's north shore for
some  observations of variable stars and meteors. Unfortunately, this
place is not in the same league as Maui for astronomy! I went as far
away as possible from Honolulu (25mi) without taking a swim, but still
the light pollution significantly degrades the sky.

And the site quality may have affected my results, because only 5
meteors were seen in 1hr Teff. I used to see 7 or 8+ on Maui. However,
the results may be useful, because I made a special effort to look out
for the reported "Delta VIR" radiant near 12:50 +05°. I had one good
candidate for this radiant. It was a mag 4, and passed south through
Corvus at medium slow velocity. The path length/radiant criteria was
valid as well. Later on, I saw a fainter mag 5, which intersected the
mag 4 one around 13:00 +10°, so this may have been another one, but it
was significantly faster, so I logged it as a SPO.

OBS: Mike Linnolt (LINMI)
DATE: Apr. 07, 2000
TIME: 0908 - 1010 UT (11:08pm - 12:10am HST night of Apr 06/07)
LOC: Dillingham, Oahu, HI (21° 34' N, 158° 12m W)
ELEV: 3m
Conditions: Mostly Clear. Temp 65F. RH 90%. Winds calm.
METHOD: Paper


Observing Periods Summary:
==========================

# Period(UT) FOV       Teff   F    LM      Dvi* VIR  SPO
  ---------- ---       ----   -    ---     ---  ---  ---
1 0908-1010  11h +00   1.00  1.00  5.9      1    1    3

*Dvi = "Delta Virginids" radiant reported as 12:50 +05°.

Periods Detail:
===============

Period #1:
----------

Mag->_-3___-2___-1____0___+1___+2___+3___+4___+5___+6
-------+----+----+----+----+----+----+----+----+----+
Dvi:......................................1.......... = 1
VIR:.................................1............... = 1
SPO:.................................1.........2..... = 3

DEAD TIME: 2 min

Note: The Dvi, start 12:30 -18, end 12:20 -28, path length 10°,
18-23° from radiant and medium slow. Seems to fit the reported
characteristics quite well.
A mag. 5 SPO, start 11:00 -30, end 09:40 -45, swifter than the Dvi
but it intersected its path around 13:00 +10, so this one may
possibly be a candidate, too?
