Edmund Halley, William Herschel, Harlow Shapley, and Edwin Hubble were born this month.
The first photograph of a meteor was taken on November 26, 1885. The minor planet/comet 2060 Chiron or 95P/Chiron was discovered by Charles Kowal on November 1, 1977.
The peaks of the minor Southern and Northern Taurid meteor showers take place on November 5 and November 12 respectively. These streams form part of the complex associated with Comet 2P/Encke. The Full Moon severely compromises the peak of the Leonid meteor shower on the morning of November 17. Leonid meteors are debris from the periodic comet 55P/Tempel-Tuttle. Because of their high speed (71 kilometers or 44 miles per second), the Leonids produce a greater percentage of fireballs than most meteor showers.

Mercury is stationary on November 10. Greatest western elongation occurs on the night of November 17. Mercury lies less than one degree south of the much fainter Saturn in Libra on the mornings of November 25 and November 26. By the end of the month, the speedy planet brightens to magnitude -0.6.
Venus is 11 degrees above the horizon one hour after sunset on November 1. By month’s end, it stands 15 degrees high at that time. Venus reaches greatest eastern elongation on November 1. It’s situated two degrees north of the galactic center on that date. On November 6, Venus is farther south (27 degrees 10 arc minutes) than it has been since 1930. Venus is three degrees south of the bright globular cluster M22 on November 13. It lies eight degrees south of the waning crescent Moon on the evening of November 6. Venus shines brightly at magnitude -4.8 by the end of November.
Mars is located 2.5 degrees south of the tenth-magnitude barred spiral galaxy M95 in Leo as the month begins. The Red Planet departs Leo and enters Virgo on November 25. It lies six degrees north of the waning crescent Moon on November 27. Mars grows to 5.6 arc seconds in apparent size and brightens to magnitude +1.2 by month’s end.
Jupiter’s apparent diameter increases to 44.8 arc seconds and its brightness to magnitude -2.6 over the course of the month. It commences retrograde motion on November 7. Jupiter is situated five degrees north of the gibbous Moon on November 22. The shadow of Ganymede follows the Galilean satellite Callisto as it transits Jupiter on the night of November 14. Callisto’s transit ends at 11:32 p.m. EST (4:32 UT on November 15). Ganymede’s shadow exits the planet at 12:25 a.m. EST (5:25 UT) on November 15. A transit by Ganymede commences a bit more than an hour later, at 1:42 a.m. EST (6:42 UT). Double shadow transits take place on November 2, 6, 9, and 13 (UT dates).

Asteroid 20 Massalia shines at ninth magnitude as it continues on a southwestward course through southern Aries. It lies a bit more than two degrees south of the sixth-magnitude star 19 Arietis on the nights of November 11 and November 12. Asteroid 216 Kleopatra is at opposition in Taurus on November 16. For information on this year’s bright asteroids and upcoming asteroid occultation events respectively, consult www.curtrenz.com/asteroids and asteroidoccultation.com/
Comet C/2012 (ISON) travels southeastward through the constellations of Leo, Virgo, and Libra this month. The comet’s relative motion increases from approximately one degree per day as November begins to three degrees per day by mid-month and five degrees per day at perihelion. Comet ISON is positioned some 52 degrees from the Sun on November 1. It enters Virgo on November 6 and remains in that constellation until November 22. Comet ISON passes 0.4 degree south-southwest of the fourth-magnitude star Beta Virginis and 4.5 degrees south-southwest of the eighth-magnitude asteroid 4 Vesta on November 7, one degree northeast of the eleventh-magnitude spiral galaxy NGC 4030 on November 9, four degrees west-southwest of the third-magnitude star Porrima (Gamma Virginis) on November 12, 0.8 degree northwest of the eleventh-magnitude spiral galaxy NGC 4593 on November 13, and eight degrees west-northwest of the first-magnitude star Spica on November 15. The comet may shine at fifth magnitude as it glides within two degrees of Spica on the mornings of November 17 and November 18. It lies 1.3 degrees east-southeast of Spica on November 18, one day after the Full Moon. Comet ISON and Comet 2P/Encke are five degrees apart on November 21. On November 23, Comet ISON is located five degrees south of Mercury and may be as bright as third magnitude. Comet ISON, Comet 2P/Encke, the third-magnitude star Zubenelgenubi (Alpha Librae), Mercury, and Saturn lie within six degrees of one another that morning. The comet passes five degrees south of Saturn the next morning. Comet ISON may shine at first magnitude on November 26, when it’s positioned nine degrees from Mercury and ten degrees from the Sun. On November 27, it passes within seven degrees of the Sun and may shine at zero magnitude or brighter but will not be visible due to the glare of the Sun. Comet ISON reaches perihelion at approximately 2:00 p.m. EST (19:00 UT) on November 28, coming within 1,165,000 kilometers (724,000 miles) of the surface of the Sun. It passes one degree southwest of the Sun at that time. If this "fresh" comet survives its perihelion passage, it may reach a peak magnitude of -4.5 but will be very difficult to observe safely. Comet ISON heads northward after perihelion and lies six degrees north of the Sun on November 30, two days before New Moon.

Comet 2P/Encke may brighten to fifth magnitude as it heads southeastward through Virgo. The periodic comet passes less than two degrees north of the third-magnitude star Delta Virginis on November 4 and within seven degrees of the first-magnitude star Spica from November 11 to November 13. The recently discovered Comet C/2013 R1 (Lovejoy) shines at ninth magnitude in the constellation of Cancer at mid-month. In late October, Comet C/2012 X1 (LINEAR) experienced an unexpected outburst similar to that of Comet 17P/Holmes in 2007, brightening from fourteenth to eighth magnitude in Coma Berenices.

Jupiter’s apparent diameter increases to 44.8 arc seconds and its brightness to magnitude -2.6 over the course of the month. It commences retrograde motion on November 7. Jupiter is situated five degrees north of the gibbous Moon on November 22. The shadow of Ganymede follows the Galilean satellite Callisto as it transits Jupiter on the night of November 14. Callisto’s transit ends at 11:32 p.m. EST (4:32 UT on November 15). Ganymede’s shadow exits the planet at 12:25 a.m. EST (5:25 UT) on November 15. A transit by Ganymede commences a bit more than an hour later, at 1:42 a.m. EST (6:42 UT). Double shadow transits take place on November 2, 6, 9, and 13 (UT dates). Browse www.skyandtelescope.com/observing/objects/planets/3304091.html?page=1&c=y to determine transits of the central meridian by the Great Red Spot. Data on the Galilean satellites is available at www.skyandtelescope.com/observing/objects/javascript/3307071.html#
Saturn is conjunction with the Sun on November 6. It can be seen again in late November in the constellation of Libra during morning twilight. For information on the satellites of Saturn, browse skytonight.com/observing/objects/javascript/3308506.html
Uranus is in retrograde near the border of Pisces and Cetus. It’s located approximately two degrees east of the sixth-magnitude star 44 Piscium.
Neptune resumes prograde or direct motion on November 13. The eighth planet resides in central Aquarius, about three degrees west of the fifth-magnitude star Sigma Aquarii and two degrees east of the fifth-magnitude star 38 Aquarii this month.

Comet C/2012 (ISON) travels southeastward through the constellations of Leo, Virgo, and Libra this month. The comet’s relative motion increases from approximately one degree per day as November begins to three degrees per day by mid-month and five degrees per day at perihelion. Comet ISON is positioned some 52 degrees from the Sun on November 1. It enters Virgo on November 6 and remains in that constellation until November 22. Comet ISON passes 0.4 degree south-southwest of the fourth-magnitude star Beta Virginis and 4.5 degrees south-southwest of the eighth-magnitude asteroid 4 Vesta on November 7, one degree northeast of the eleventh-magnitude spiral galaxy NGC 4030 on November 9, four degrees west-southwest of the third-magnitude star Porrima (Gamma Virginis) on November 12, 0.8 degree northwest of the eleventh-magnitude spiral galaxy NGC 4593 on November 13, and eight degrees west-northwest of the first-magnitude star Spica on November 15. The comet may shine at fifth magnitude as it glides within two degrees of Spica on the mornings of November 17 and November 18. It lies 1.3 degrees east-southeast of Spica on November 18, one day after the Full Moon. Comet ISON and Comet 2P/Encke are five degrees apart on November 21. On November 23, Comet ISON is located five degrees south of Mercury and may be as bright as third magnitude. Comet ISON, Comet 2P/Encke, the third-magnitude star Zubenelgenubi (Alpha Librae), Mercury, and Saturn lie within six degrees of one another that morning. The comet passes five degrees south of Saturn the next morning. Comet ISON may shine at first magnitude on November 26, when it’s positioned nine degrees from Mercury and ten degrees from the Sun. On November 27, it passes within seven degrees of the Sun and may shine at zero magnitude or brighter but will not be visible due to the glare of the Sun. Comet ISON reaches perihelion at approximately 2:00 p.m. EST (19:00 UT) on November 28, coming within 1,165,000 kilometers (724,000 miles) of the surface of the Sun. It passes one degree southwest of the Sun at that time. If this "fresh" comet survives its perihelion passage, it may reach a peak magnitude of -4.5 but will be very difficult to observe safely. Comet ISON heads northward after perihelion and lies six degrees north of the Sun on November 30, two days before New Moon.

Comet 2P/Encke may brighten to fifth magnitude as it heads southeastward through Virgo. The periodic comet passes less than two degrees north of the third-magnitude star Delta Virginis on November 4 and within seven degrees of the first-magnitude star Spica from November 11 to November 13. The recently discovered Comet C/2013 R1 (Lovejoy) shines at ninth magnitude in the constellation of Cancer at mid-month. In late October, Comet C/2012 X1 (LINEAR) experienced an unexpected outburst similar to that of Comet 17P/Holmes in 2007, brightening from fourteenth to eighth magnitude in Coma Berenices.
