Observer: David Oesper, SE of Alpine, TX
About 5% sky obstruction at this site due to trees and buildings
0249 Begin zenithal sky brightness measurements with Sky Quality Meter
21.84 21.80 21.80 21.78 21.76 21.76 21.77 magnitudes/square arcsecond
Average: 21.79 Limiting magnitude: 6.5 Sensor Temp = 17˚ C
Empirical formula: (Avg-8.89)/2 + 0.04
0300 Begin observations, sky conditions clear and windy
note: all meteors are white unless otherwise noted
0306 T+2: fairly slow meteor, Ari-->Square of Peg, probable South Taurid, 10˚
0323 S+3: parallel eastern side Sq. of Peg, coming from dir of Beta Cas, flared, 20˚
0327 S+2: parallel western side Sq. of Peg, coming from dir of Zeta Cep, 5˚
note: 0323 & 0327 meteors could have come from the same radiant in Cep
0334 S+3: Cam-->horizon, radiant in Cas? peripheral, somewhat uncertain
note: sky is dark enough I can nicely see the Milky Way going down through Aur
note: can’t see M33 in Tri but NGC 752 in And is very noticeable
0408 note: Betelgeuse is just clearing the garage (alt. = 5˚)
0410 note: rapid-fire flashes very low, over towards Betelgeuse (azi. ~ 84˚)
probably very distant thunderstorm
note: one of the nice things about living in the Big Bend region of West Texas is the lack of air traffic; haven’t seen a single plane anywhere in the sky this session
0414 note: brighter flash, more localized, below and 3-4˚ to the right of Betelgeuse
0416 T?+3: Eri-->horizon, coming from dir of Aldebaran, peripheral, 10˚
note: another flash below Ori
0431 S+2: Per-Tau border-->Aur, coming from dir to left of the Pleiades, Ari, 10˚
0436 note: another flash, below and to the left of Betelgeuse; must be very distant thunderstorm as it is completely clear here and was all day, too; no forecast of rain
note: 52 & 53 Cas are part of what looks like a cluster of stars, right off the end of Cas; Delta Cas & Epsilon Cas point towards it
0448 note: another flash, below and to the left of Betelgeuse
0456 T+2: slow, southern Per-->Polaris, peripheral, 20˚
0457 T+1: about the same path as 0456 meteor
0457 T+3: to the right of the Pleiades-->Belt of Ori
0500 End observations
0502 Begin zenithal sky brightness measurements
21.82 21.89 21.84 21.84 21.83 21.80 21.82 mag/sq.˝
Average: 21.83 Limiting magnitude: 6.5 Sensor Temp = 8˚ C
0300-0500 UT 2, Nov 2010, Teff = 2.0
5 Taurids [magnitudes +1 (1), +2 (2), +3 (2)]
4 Sporadics [magnitudes +2 (2), +3 (2)]
