This astronomy calendar of celestial events contains dates for notable celestial events including moon phases, meteor showers, eclipses, occultations, oppositions, conjunctions, and other interesting events. Most of the astronomical events on this calendar can be seen with unaided eye, although some may require a good pair of binoculars for best viewing. Many of these events and dates used here were obtained from the U.S. Naval Observatory, the NASA/Goddard Space Flight Center, and The Old Farmer's Almanac. Events on the calendar are organized by date and each is identified with an astronomy icon as outlined below. Times given in Coordinated Universal Time (UTC) must be converted to your local time. You can use the UTC clock below to figure out how many hours to add or subtract for your local time.
January 1 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 11:14 UTC.
January 3, 4 - Quadrantids Meteor Shower. The Quadrantids are an above average shower, with up to 40 meteors per hour at their peak. The shower usually peaks on January 3 & 4, but some meteors can be visible from January 1 - 5. Best viewing will be from a dark location after midnight. A thin, crescent moon will set early in the evening leaving dark skies for what should be a great show. Look for meteors radiating from the constellation Bootes. Be sure to find a dark viewing location far from city lights.
January 5 - Jupiter at Opposition. The giant planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Jupiter and its moons.

These meteors can produce bright dust trails that last for several seconds. The shower usually peaks on April 21 & 22, although some meteors can be visible from April 16 - 25. The last quarter moon will be hanging around for the show, and could hide some of the faintest meteors. Look for meteors radiating from the constellation of Lyra after midnight. Find a dark location far from city lights.

The theme of Astronomy Day is "Bringing Astronomy to the People," and on this day astronomy and stargazing clubs and other organizations around the world will plan special events. You can find out about special local events by contacting your local astronomy club or planetarium. You can also find more about Astronomy Day by checking the Web site for the Astronomical League.

July 28, 29 - Southern Delta Aquarids Meteor Shower. The Delta Aquarids can produce about 20 meteors per hour at their peak. The shower usually peaks on July 28 & 29, but some meteors can also be seen from July 18 - August 18. The radiant point for this shower will be in the constellation Aquarius. A thin, crescent moon will disappear early in the evening leaving dark skies for what should be a good show. Best viewing is usually to the east after midnight from a dark location.
August 10 - Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 18:09 UTC.
August 12, 13 - Perseids Meteor Shower. The Perseids is one of the best meteor showers to observe, producing up to 60 meteors per hour at their peak. The shower's peak usually occurs on August 13 & 14, but you may be able to see some meteors any time from July 23 - August 22. The radiant point for this shower will be in the constellation Perseus. The nearly full moon will be a problem this year by hiding most of the fainter meteors in its glare. But with nearly 60 meteors per hour possible, this should still be a good show. Find a location far from city lights and look to the northeast after midnight.
August 18 - Conjunction of Venus and Jupiter. The two bright planets will come unusually close to each other, only a quarter of a degree, in the early morning sky. Also, the beehive cluster in the constellation Cancer will be only 1 degree away. Look to the east just before sunrise.
August 25 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 14:13 UTC.
August 29 - Neptune at Opposition. The blue planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view Neptune. Due to its distance, it will only appear as a tiny blue dot in all but the most powerful telescopes.
September 9 - Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 01:38 UTC.
September 23 - September Equinox. The September equinox occurs at 02:29 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of fall (autumnal equinox) in the northern hemisphere and the first day of spring (vernal equinox) in the southern hemisphere.

You can find out about special local events by contacting your local astronomy club or planetarium. You can also find more about Astronomy Day by checking the Web site for the Astronomical League.
October 7 - Uranus at Opposition. The blue-green planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view Uranus. Due to its distance, it will only appear as a tiny blue-green dot in all but the most powerful telescopes.
October 8 - Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 10:51 UTC.
October 8 - Total Lunar Eclipse. The eclipse will be visible throughout most of North America, South America, eastern Asia, and Australia. (NASA Map and Eclipse Information)

A good show could be experienced on any morning from October 20 - 24, and some meteors may be seen any time from October 17 - 25. An extremely thin, crescent moon will hang around for the show, but it shouldn’t cause any problems this year. Best viewing will be to the east after midnight. Be sure to find a dark location far from city lights.

November 6 - Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 22:23 UTC.
November 17, 18 - Leonids Meteor Shower. The Leonids is one of the better meteor showers to observe, producing an average of 40 meteors per hour at their peak. The shower itself has a cyclic peak year every 33 years where hundreds of meteors can be seen each hour. The last of these occurred in 2001. The shower usually peaks on November 17 & 18, but you may see some meteors from November 13 - 20. The crescent moon could hide some of the faintest meteors this year, but with up to 40 meteors per hour, this should still be a great show. Look for the shower radiating from the constellation Leo after midnight.
November 22 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 12:32 UTC.
December 6 - Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 12:27 UTC.
December 13, 14 - Geminids Meteor Shower. Considered by many to be the best meteor shower in the heavens, the Geminids are known for producing up to 60 multicolored meteors per hour at their peak. The peak of the shower usually occurs around December 13 & 14, although some meteors should be visible from December 6 - 19. The radiant point for this shower will be in the constellation Gemini. The near last quarter moon will be hanging around for the show, but with nearly 60 meteors per hour possible, this should still be an excellent show. Best viewing is usually to the east after midnight from a dark location.
December 21 - December Solstice. The December solstice occurs at 23:03 UTC. The South Pole of the earth will be tilted toward the Sun, which will have reached its southernmost position in the sky and will be directly over the Tropic of Capricorn at 23.44 degrees south latitude. This is the first day of winter (winter solstice) in the northern hemisphere and the first day of summer (summer solstice) in the southern hemisphere.
December 22 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 01:36 UTC.
