(meteorobs) Meteor Activity Outlook for October 13-19, 2012

Sat Oct 13 17:17:44 EDT 2012

To capture Meteor Video, I recommend 4 things; a CAMERA, LENS, ENCLOSURE,
and SOFTWARE.

1.       CAMERA, Hauppauge HB-710E - Yes it is expensive, because it has
very deep sensitivity, a large sensor, low dark current, and high dynamic
range, plus other things too numerous to mention. Buy one from many
different suppliers, without a lens.

2.       LENS, (Also Expensive) The lens of choice is the Rainbow L163VDC4P
but they are not made any longer. An alternative lens is the Fujinon
FE185C046HA-1, but it does not have an Auto-Iris.

3.       ENCLOSURE, Go to your Home Store, buy a 4 in. PVC Sewer Cleanout,
the one with the "T" screw-in cover, a PVC 4 in. cover, and a 4 in. screw-in
cover. Go online to a Security Camera Company like "Super Circuits" and
purchase a clear 4 inch dome. Epoxy the dome to the end of the Server
Cleanout. Mount the Lens/Cover assembly inside the Dome. Mount the
Cleanout/Camera/Lens Assembly to a Telescoping Mast. 

4.       SOFTWARE, "UFO Capture" "UFO Analyzer" "SENTINEL" "ASGARD"

Hi Robert,
Enjoying reading your outlook articles!
I wanted to ask you what are the chances of Lunar Impacts being visible
through the Orionids peak, will the first quarter moon be in a position to
intersect the stream?
How should one go about capturing video, i know with lunar occultations it's
very hard to capture a mag 5 star near the dark limb due to overexposing the
bright limb.
Any flashes would have to be around mag 2 or 3 to be easily visible on a
dark limb, what are the normal magnitudes of meteor impacts that have been
recorded?
I intend to have go if you think it's worth trying for at this lunar phase.

Cheers,

At this time the moon is located near the sun and is invisible at night. As
the week progresses the waxing crescent moon will enter the evening sky but
will not interfere with meteor observing. The estimated total hourly meteor
rates for evening observers this week is near four for observers located at
mid-northern latitudes and three for observers in mid-southern latitudes.
For morning observers the estimated total hourly rates should be near twenty
from the mid-northern hemisphere and thirteen from the mid-southern
hemisphere. The actual rates will also depend on factors such as personal
light and motion perception, local weather conditions, alertness and
experience in watching meteor activity.
> 
> The radiant (the area of the sky where meteors appear to shoot from)
positions and rates listed below are exact for Saturday night/Sunday morning
October 13/14. These positions do not change greatly day to day so the
listed coordinates may be used during this entire period. Most star atlases
(available at science stores and planetariums) will provide maps with grid
lines of the celestial coordinates so that you may find out exactly where
these positions are located in the sky. A planisphere or computer
planetarium program is also useful in showing the sky at any time of night
on any date of the year. Activity from each radiant is best seen when it is
positioned highest in the sky, either due north or south along the meridian,
depending on your latitude. It must be remembered that meteor activity is
rarely seen at the radiant position. Rather they shoot outwards from the
radiant so it is best to center your field of view so that the radiant lies
at the edge and not the center.
> Viewing there will allow you to easily trace the path of each meteor back
to the radiant (if it is a shower member) or in another direction if it is a
sporadic. Meteor activity is not seen from radiants that are located below
the horizon. The positions below are listed in a west to east manner in
order of right ascension (celestial longitude). The positions listed first
are located further west therefore are accessible earlier in the night while
those listed further down the list rise later in the night.
> 
> The following radiants are expected to be active this week:
> 
> The center of the large Southern Taurid (STA) radiant is currently located
at 02:24 (036) +10. This position lies near on the Cetus/Aries border. The
fourth magnitude star Xi 2 Ceti lies two degrees southeast from the center
of the radiant. The radiant is so large that Southern Taurid activity may
also appear from eastern Pisces, Aries, northern Cetus, northern Eridanus,
and western Taurus. This radiant is best placed near 0200 local daylight
time (LDT), when it lies on the meridian and is located highest in the sky.
Maximum occurred on October 9th, but rates remain near maximum levels of
three per hour for a week after this date. With an entry velocity of 29
km/sec., the average Southern Taurid meteor would be of slow velocity.
> 
> The Orionids (ORI) are producing 3-5 shower members per hour during the
last few hours before dawn, when the radiant lies highest in the sky. The
radiant is currently located at 06:00 (090) +16, which is in the
northeastern Orion, eight degrees northwest of the brilliant first magnitude
orange star Betelgeuse (Alpha Orionis). Orionid meteors are equally well
seen either side of the equator. With an entry velocity of 67 km/sec., most
activity from this radiant would be swift. Maximum activity is predicted to
occur on the 22nd when hourly rates should be near twenty.
> 
> The Epsilon Geminids (EGE) are active all month long with low hourly
rates. Even at maximum activity only three shower members per hour are
expected. Recent research by the IMO has indicated an earlier maximum of
October 15th, rather than October 19th. The radiant position is currently
located at 06:27 (097) +29. This position actually lies within the borders
of Auriga, just east of the faint star Kappa Aurigae. The radiant is also
best placed during the last dark hour before dawn, when it lies highest
above the horizon in a dark sky. Rates would be near two per hour as seen
from the northern hemisphere and less than one per hour as seen south of the
equator. With an entry velocity of 70 km/sec., most activity from this
radiant would be swift.
> 
> Studies of the IMO's video database by Sirko Molau and Juergen Rendtel has
revealed a radiant active in Lynx this time of year. Earlier visual
observations of this activity placed the radiant in eastern Auriga.
Therefore the radiant is known as the Psi Aurigids (PSA). This radiant is
active from October 8-18, with maximum activity occurring on the 12th. The
radiant drift is not well established as positions jump around quite a bit
during its ten day activity period. At maximum the radiant is located at
07:36 (113) +47. This position lies in a remote area of central Lynx. The
nearest bright star is second magnitude Castor (Alpha Geminorum), which lies
fifteen degrees to the south. This is a weak display and even at maximum
activity rates would most likely be less than one shower member per hour, no
matter you location. With an entry velocity of 68 km/sec., most activity
from this radiant would be swift.
> 
> Studies of the IMO's video database by Sirko Molau and Juergen Rendtel has
also revealed a radiant active in Ursa Major this time of year. The October
Ursae Majorids (OCU). are active from October 15-20, with maximum activity
occurring on the 16th. At maximum the radiant is located at 09:36 (144) +65.
This position lies in western Ursa Major, near the faint star 23 Ursae
Majoris. This area of the sky is best placed during the last hour before
morning twilight, when it lies highest above the horizon in a dark sky. At
maximum activity rates would most likely be 1-2 per hour. Due to the high
northern location of this radiant, these meteors are not well seen from the
southern hemisphere. With an entry velocity of 54km/sec., most activity from
this radiant would be medium-swift.
> 
> The Leonis Minorids (LMI) are active from October 16-27 with maximum
activity occurring on October 23rd. Hourly rates would be less than one this
week. This radiant is currently located at 10:16 (154) +38, which places it
in northern Leo Minor, two degrees northwest of the fourth magnitude star
Beta Leonis Minoris . The radiant is best placed just before dawn when it
lies highest in a dark sky. This shower is better situated for observers
situated in the northern hemisphere where the radiant rises far higher into
the sky before the start of morning twilight. At 60km/sec., the average
Leonis Minorid is swift.
> 
> As seen from the mid-northern hemisphere (45N) one would expect to see
approximately ten sporadic meteors per hour during the last hour before dawn
as seen from rural observing sites. Evening rates would be near three per
hour. As seen from the mid-southern hemisphere (45S), morning rates would be
near five per hour as seen from rural observing sites and two per hour
during the evening hours. Locations between these two extremes would see
activity between the listed figures.
