What’s in the Sky in November
- 2nd Saturn at mag. 0.7 rising 11:49hr AEDT, Dist. 1,442,603,653km. Tilt of Saturn’s North pole towards Earth is 15.2591 degrees.
- 2nd Jupiter is a brilliant evening object during November rising at 16:35AEDT, mag. -2.8, dist. 620,876,832km, tilt of North Pole towards Earth is 2.3626 degrees.
- 2nd Venus at mag. -4.0 and rising just after the Sun at 06:28hrs AEDT, Dist. 256.336,497km.
- 2nd Mars is a late night object rising at 23:36AEDT a very distant object Mag. -1.3 Dist. 92,101,928km. Tilt of North pole towards Earth is 0.5803 degrees. Mars is coming lcoser to earth and will reach opposition on 8th December.
- 2nd Mercury is an early morning object rising at 06:09hrs AEDT just before the Sun. Mag. -0.41.5, dist. 210,359,993km. Tilt of North Pole towards earth is 0.7757degrees.
- 8th Total Lunar Eclipse special event.
- 12th The two Taurid Meteor Shower branches reach their highest rates around October 10 (Southern Taurids, 002 STA) and November 12 (Northern Taurids, 017 NTA), respectively. Both dates are close to the Moon’s full phase. However, observers should be alert as 2022 is again a “Taurid swarm” year after 2012 and 2016. Meteoroids concentrated in resonant orbits may result in higher rates and may include larger objects, causing bright fireballs between end October and about November 10. This is an early morning event, image is for 03:30hrs AEDT.
- 13th Moon Lowest, 28 degrees Nth.
- 17th Leonids Meteor shower peak is 23hrs UT (10:00hrs AEDT on 18th Nov) best visibility at predawn.
Leonids (LEO)Active: November 6—30; Z ~ 10; V∞ = 71 km/s.
The parent comet of this shower, 55P/Tempel-Tuttle, passed its perihelion last in 1998, more than two decades ago now. Meanwhile the comet has passed its aphelion. The knowledge of the dust ejection mechanisms and trail evolution allowed us to predict and verify variable activity in numerous years until recently.
The nodal Leonid maximum occurs on 2022 November 17.
Additionally, there are a few encounters with dust trails in the following days:
Model calculations of Maslov (2007) and Sato (2021) show an approach of the 1733 dust trail on November 19. Maslov gives 06h UT, Sato obtains 06h20m 06h27m UT ( = 236 :576
and = 236 :581; dierent ejection velocities).
The possible activity level depends on the ejection velocity (which has a negative sign in this case and observations of meteors from such trails are scarce).
Maslov adds: meteors should be bright, a ZHR of 200+ seems possible despite the uncertainties. Sato comments: ZHR may
reach 50+ because the model suggests that the dust tends to be concentrated.
18 IMO INFO(3-21)
An encounter with the 1600 trail (weak rate possible near November 18, 07h UT; =235 :6) is found by Vaubaillon (2021). A weak rate enhancement may be visible due to the 1800
trail later on November 21, 15h UT (Maslov, 2007).
The nodal maximum occurs just after the Moon’s last quarter phase, and the conditions are slightly better for the later encounters. Visual observers need to shield the direct moonlight. The shower’s radiant is usefully observable only after local midnight or so north of the equator, later for places further south.Credit:IMO.
Right: Engraving by Adolf Vollmy (1889)
This famous engraving of the 1833 Leonid meteor shower was produced for the Adventist book Bible Readings for the Home Circle by Adolf Vollmy. It’s based on a painting by Swiss artist Karl Jauslin, which, in turn, was based on a first-person account of the 1833 storm by a minister, Joseph Harvey Waggoner, who saw the 1833 shower on his way from Florida to New Orleans.
In that famous shower, hundreds of thousands of meteors per hour were seen! It was the first recorded meteor storm of modern times.
- 26th Moon at Perigee 12:34 AEDT Perigee distance 362,825.6km
- 26th Moon at it’s highest altitude 27 Degrees.
- 21st Alpha Monocerotids Meteor Shower Peak in the evening.
Monocerotids (246 AMO) Active: November 15– 25; Maximum: November 21st 23:30hrs UT (10:30hrs AEDT 22nd Nov) ; ZHR up to 5; V∞ = 42 km/s.
The most recent -Monocerotid outbursts have been observed in 1995 (ZHR 420) and 2019 (ZHR 120). In both cases, the peak lasted for just ve minutes, the entire outbursts 30 minutes. The next strong AMO outburst is unlikely before 2043. Despite all this, observers are
advised to monitor the AMO annually to complete our knowledge about this stream. New Moon on November 23 provides us with favourable observing conditions. Credit: IMO.
