Astronomical Calendar 2013 Astronomy Events

 

03.04 January 2013 - Quadrantid meteor shower, get to have up to 40 meteors per hour, usually on 3 and 4 January, but may be visible on 1-5 January. The highest rate of meteors per hour took place in 1932 (80/ hour). The best time for observations is a dark place after midnight. Meteors radiate from the constellation Bootes, close to the North Star.
The source of this meteor shower was unknown until December 2003 when Peter Jenniskens of the Ames Research Center (NASA) found evidence that meteoroids come from 2003 EH1 , an “asteroid”, which is probably a piece of a comet which collapsed 500 years ago.

December 3 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 00:22 UTC.

December 13, 15 - 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 gibbous moon could be a problem this year, hiding man of the fainter meteors. But with up to 60 meteors per hour predicted, this should still be a good show. Best viewing is usually to the east after midnight from a dark location.

December 21 - December Solstice. The December solstice occurs at 17:11 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.

  • Perihelion - the position in a planet's orbit closest to the Sun
  • Aphelion - the position in a planet's orbit furthest from the Sun
  • Perigee - the position in the Moon's orbit closest to Earth
  • Apogee - the position in the Moon's orbit furthest from Earth
  • Inferior Conjunction - Mercury or Venus passes between Earth and the Sun
  • Superior Conjunction - Mercury or Venus passes on the opposite side of the Sun from Earth
  • Greatest Elongation - elongation is the angle between the Sun and a planet as seen from Earth; during eastern elongation (E), the planet appears as an evening star; during western elongation (W), the planet appears as a morning star
  • Opposition - the position in a planet's orbit when it appears opposite the Sun as seen from Earth
  • Conjunction - the position in a planet's orbit when it appears closest the Sun as seen from Earth
  • Occultation - the Moon occults or eclipses a star or planet
  • Ascending Node - the point where a planet crosses from the southern to northern portion of its orbit
  • Descending Node - the point where a planet crosses from the northern to the southern portion of its orbit
