COMET GIACONINI-ZINNER, P21, is expected to fade to magnitude 10.4 by the beginning of November.

COMET 46P, Wirtanen starts November as a magnitude 11.1 object in Sculptor. By November 21 the comet should have brightened to magnitude 9.5, it will then transit at 10.57 pm. Wirtanen moves into Cetus on the 27th with a magnitude 9.1. It is expected to brighten to magnitude 8.8 by the end of November. (Data taken from GUIDE.)

The comet will be brightest mid December, but magnitude estimates vary considerably.

PLANETS in November 2018.

MERCURY is an evening object most of November, but best seen as such in the earlier part of the month when it sets just over 2 hours after the Sun. It is at its greatest elongation 23° east of the Sun on the 6th. The planet is in Scorpius at first starting the month about 4.5° from Jupiter. It then moves into Ophiuchus skirting the border with Scorpius. While there it passes Antares, the two being 1.8° apart on the 9th.

Mercury is stationary on the 17th after which it starts moving back towards the west so passing Antares again on the 23rd. This time the two will be 4° apart. By then Mercury will set 46 minutes after the Sun and so be low in the early twilight and difficult to see, especially with a magnitude 2.1.

For the rest of the month Mercury will be too close to the Sun for observation. It is at inferior conjunction, between Earth and Sun on the 27th after which it is a morning object.

VENUS is a morning object during November, gradually rising earlier before the Sun. It is in Virgo and will be about 1.25° from Spica mid month. The planet will also be stationary at the time, after which it starts moving to the east on a path which takes it away from Spica again.

MARS starts November in Capricornus setting well after midnight all month. Thus it well placed in the evening sky for viewing. It moves into Aquarius on the 11th. Mars continues to fade slowly during the month, by will still be at magnitude 0 by the 30th.

The moon, just after first quarter, is 1.5° from Mars on the evening of the 16th. During the afternoon the two will be much closer, just over half a degree apart. The moon then occults Mars, the event is only visible at night from southern parts of South America. A daytime event occurs for much of the Antarctic continent

JUPITER is a low, early evening object at the start of November, but soon will be too close to the Sun for observation.

The planet is at conjunction with the Sun on November 26 when it will be 802 million km beyond the Sun, that is 950 million km, 6.35 AU, from the Earth.

After conjunction Jupiter become a morning object but is not observable for the remainder of the month.

SATURN continues to move through Sagittarius during November. It sets about 4.5 hours after the Sun on the 1st, reducing to just over two hours later on the 30th. So it will be best viewed as an early evening object.

On the evening of the 11th the crescent moon will be 4.5° from Saturn at about 10 pm. The separation of the two will be half that 6 hours later, well after they set in NZ.

URANUS, in Aries, rises well before sunset, especially at the end of November. Thus it will be well placed for evening viewing. It ends the month poised to move into Pisces.

NEPTUNE is an evening object in Aquarius setting some hours after midnight. The planet is stationary on the 25th so shows little change in position during the month. On the 17th the moon, some two days after first quarter, will be 2° above Neptune as seen from NZ at 10 pm.

PLUTO, in Sagittarius, is 5° from the crescent moon on the evening of the 12th. The two are considerably closer later that night after they set in NZ An occultation of the planet occurs, "visible" from western Europe. The glare from the moon means the event will not be observable.

CERES
starts to move into the morning sky during November. It rises only 3 minutes before the Sun on the 1st, advancing to 1 hour earlier on the 30th. It will remain too low for observation.

PALLAS, also a morning object, is better placed than Ceres for observing. In Virgo it moves in the direction of Spica, and Venus, during the month. Pallas rises 80 minutes before Spica at the end of November.

JUNO is at opposition on November 17 at magnitude 7.4. It will be the brightest asteroid throughout November. Just south of the celestial equator, it will have a maximum altitude of around 50° in New Zealand.

VESTA, mostly an evening object, sets a little after midnight. During November it moves away from Saturn and the handle of the "teapot" in Sagittarius to cross into Capricornus on the 30th.

HEBE rises late evening during November. During the month the asteroid's path describes a small hook in Monoceros, Pallas being stationary on the 12th. It will be about midway between Betelgeuse and Procyon.
