At magnitude 2. Sharp eyes, or binoculars, reveal that it's yellow-orange; it's a K 3 supergiant. At 6th magnitude M15 is within binocular range as a tiny glowball, and a 6-inch telescope may begin to resolve some of its sugarpile starspecks. EDT, followed by Io's tiny black shadow at p. Each takes about 1 hour 40 minutes to cross the planet. Meanwhile on Jupiter itself, the Great Red Spot should cross Jupiter's central meridian around p.
EDT p. The Red Spot is in fine position for a good 50 minutes before and after its transits. A light blue or green filter at the eyepiece helps to reveal it. The ten featured galaxies are magnitudes 12 to Eastern Daylight Time. The half-lit Moon rises around midnight, in Cancer far below Castor and Pollux. Once the Moon is nicely up, the night is late enough that you're getting a fine preview of the winter evening sky.
Spot Procyon two or three fists at arm's length right of the Moon, and brilliant Sirius the same distance right of Procyon. Look for the Pleiades cluster about three fists at arm's length to Capella's right. These harbingers of the cold months rise higher as evening grows late — and watch for Aldebaran coming up below the Pleiades. Upper right of Capella, and upper left of the Pleiades, the stars of Perseus lie astride the Milky Way. Above Altair lurk two distinctive little constellations: Delphinus the Dolphin, hardly more than a fist at arm's length to Altair's upper left, and smaller, fainter Sagitta the Arrow, slightly less far to Altair's upper right.
Light pollution too bright? Use binoculars! M ercury , at the neck of stick-figure Virgo, is having its best morning apparition of the year. Look for it low above the horizon in early dawn 60 to 40 minutes before your sunrise time, just a little south of due east.
It's brightening day by day: from magnitude —0. Venus , brilliant at magnitude —4. Venus now stays up about 45 minutes after twilight's end. It will continue to get higher and brighter into early December. Jupiter is the bright one at magnitude —2. In twilight they're almost the same height, just beginning to tilt. As evening advances they tilt ever more steeply as they move westward. Saturn sets around midnight daylight-saving time, followed by Jupiter about an hour later.
Here's a beginner's telescopic guide to Jupiter. Uranus magnitude 5. Under dark skies, M31 can be seen with unaided eyes as a faint smudge located 1. Binoculars green circle will reveal the galaxy very well. The moon will officially reach its third quarter phase at a. At third quarter our natural satellite always appears half-illuminated, on its western side - towards the pre-dawn sun. It rises in the middle of the night and remains visible in the southern sky all morning.
The name for this phase reflects the fact that the moon has completed three quarters of its orbit around Earth, measuring from the previous new moon. The ensuing week of moonless evening skies will be ideal for observing deep sky targets. On Saturday, November 27, the dwarf planet Ceres will reach opposition, its closest approach to Earth for the year — a distance of On the nights around opposition, Ceres will shine with a peak visual magnitude of 7, well within reach of binoculars and backyard telescopes.
Ceres will already be climbing the eastern sky after dusk. It will reach its highest elevation, and peak visibility, over the southern horizon at about midnight local time. The pair will begin to cross at p. EST, which converts to p. CST, p. MST, p. The transit will last for approximately 2 hours.
For observers in the western USA and Canada, only the later stages of the event will be occurring in a dark sky. During the first week of November, Mercury will be completing its best morning apparition for the year for mid-Northern latitude observers — so the planet will be quite easily visible, shining at magnitude Viewed in a telescope during that period, Mercury will show a waxing gibbous i.
From mid-northern latitudes, their best viewing time will be after about 6 a. Observers at tropical latitudes will see the two planets higher and in a darker sky. After mid-month, Mercury will be too close to the sun for observing while it approaches superior solar conjunction on November Venus reached its widest separation from the sun towards the end of October, but its position well south of a canted-over evening ecliptic will keep the brilliant, magnitude Meanwhile, Southern Hemisphere observers, where the nearly vertical ecliptic has allowed the planet to sit relatively high in a dark sky, have experienced a terrific apparition.
Viewed through a telescope during November, our sister planet will show a gradually waning, less than half-illuminated phase and an apparent disk diameter that swells dramatically from 26 to On November 7, the young crescent moon will shine several finger widths to the lower right or 5 degrees to the celestial west of planet Venus. From mid-Northern latitudes, the magnitude 1. A very close conjunction with Mercury on November 10 may be worthy of setting the alarm.
Before the end of November, Mars will be elongated enough to briefly shine in a relatively dark sky, among the stars of Libra. The earlier sunsets during November will extend our evening Jupiter -viewing time. The magnitude Views of Jupiter in amateur telescopes will show dark equatorial bands across its disk, which will shrink from 42 to 38 arc-seconds during the month. The Great Red Spot will appear for a few hours every 2nd or 3rd night.
During November, Saturn will be observable during early evening while it travels prograde eastward through the faint stars of western Capricornus. The magnitude 0. Viewed in a telescope, Saturn will display a mean apparent disk diameter of Several moons can be readily seen arrayed around the planet, especially the brightest one, Titan.
Uranus will reach opposition on November 5, making it an all-night target during November. On opposition night it will be closest to Earth for this year - a distance of 1. It will also appear slightly larger - showing a 3. On November 17, the very bright, nearly-full moon will shine two thumb widths to the lower left or 2.
The distant, blue planet Neptune will be observable until after midnight during November. The magnitude 7. If the sky is very dark, Neptune can be seen in good binoculars. Your best views will come in mid-evening, when the blue planet is highest in the south.
Asterism: A noteworthy or striking pattern of stars within a larger constellation. Degrees measuring the sky : The sky is degrees all the way around, which means roughly degrees from horizon to horizon. It's easy to measure distances between objects: Your fist on an outstretched arm covers about 10 degrees of sky, while a finger covers about one degree.
