May 2013 Astronomy Dates

• May 4, 5 - Eta Aquarids Meteor Shower. The Eta Aquarids is an above average shower, capable of producing up to 60 meteors per hour at its peak. Most of the activity is seen in the Southern Hemisphere. In the Northern Hemisphere, the rate can reach about 30 meteors per hour. It is produced by dust particles left behind by comet Halley, which has known and observed since ancient times. The shower runs annually from April 19 to May 28. It peaks this year on the night of May 4 and the morning of the May 5. The second quarter moon will block out some of the less bright meteors this year but you should still be able to see quite a few good ones if you are patient. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.
• May 10 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 00:28 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
• May 10 - Annular Solar Eclipse. An annular solar eclipse occurs when the Moon is too far away from the Earth to completely cover the Sun. This results in a ring of light around the darkened Moon. The Sun's corona is not visible during an annular eclipse. The path of the eclipse will begin in western Australia and move east across the central Pacific Ocean. (NASA Map and Eclipse Information)
• May 25 - 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 04:25 UTC. This phase occurs at 11:09 UTC. This full moon was known by early Native American tribes as the Full Flower Moon because this was the time of year when spring flowers appeared in abundance. This moon has also been known as the Full Corn Planting Moon and the Milk Moon.
• May 28 - Conjunction of Venus and Jupiter. Conjunctions are rare events where two or more objects will appear extremely close together in the night sky. The two bright planets will be within 1 degree of each other in the evening sky. The planet Mercury will also will also be visible nearby. Look to the west near sunset.
• May 25 - Penumbral Lunar Eclipse. A penumbral lunar eclipse occurs when the Moon passes through the Earth's partial shadow, or penumbra. During this type of eclipse the Moon will darken slightly but not completely. The eclipse will be visible throughout most of North America, South America, western Europe, and western Africa.

June 2013 Astronomy Dates

• June 8 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 15:56 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
• June 12 - Mercury at Greatest Eastern Elongation. The planet Mercury will be at its furthest angle from the Sun, known as greatest elongation. It will be at its highest point in the night sky after sunset. This is the best time to try to view Mercury since it stays so close to the Sun and doesn't usually climb very high above the horizon. 
• June 21 - June Solstice. The June solstice occurs at 05:04 UTC. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.
• June 8 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 15:56 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
• June 23 - 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 11:32 UTC. This full moon was known by early Native American tribes as the Full Strawberry Moon because it signaled the time of year to gather ripening fruit. It also coincides with the peak of the strawberry harvesting season. This moon has also been known as the Full Rose Moon and the Full Honey Moon.

July 2013 Astronomy Dates

• July 8 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 07:14 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
• July 22 - 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 18:15 UTC. This full moon was known by early Native American tribes as the Full Buck Moon because the male buck deer would begin to grow their new antlers at this time of year. This moon has also been known as the Full Thunder Moon and the Full Hay Moon.
• July 27, 28 - Delta Aquarids Meteor Shower. The Delta Aquarids is an average shower that can produce up to 20 meteors per hour at its peak. It is produced by debris left behind by comets Marsden and Kracht. The shower runs annually from July 12 to August 23. It peaks this year on the night of July 27 and morning of July 28. The second quarter moon will block out most of the faint meteors, but you should still be able to catch quite a few good ones if you are patient. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.
