Super Moon
June 2013
Perigee Moon
This Weekend
Set to peak on Sunday, June 23, the 2013 supermoon is noteworthy not only for the remarkable sight it will present to skywatchers but also because it will be the largest supermoon this year.
Also known as a perigee moon, the event occurs when a full moon lines up with the Earth and the sun at a specific point in its orbit, called the lunar perigee. That's the point at which the moon is nearest to Earth as it traces its elliptical path around our planet.
Also known as a perigee moon, the event occurs when a full moon lines up with the Earth and the sun at a specific point in its orbit, called the lunar perigee. That's the point at which the moon is nearest to Earth as it traces its elliptical path around our planet.
Since it's closer to us, the moon appears up to 14 percent bigger and 30 percent brighter than usual. Coined by astrologer Richard Nolle, the term "supermoon" essentially means a bigger and brighter full moon.
While skywatchers will be able to spot another supermoon in July, the moon will not be this close again until August 2014.
The moon will turn full at 7:32 a.m. EDT Sunday. It will reach its closest point to the Earth 22 minutes earlier and will be visible after the sun sets that evening.
So be sure to step outside Sunday night to catch a glimpse of the June 2013 supermoon. (To see the perigee moon in all its oversized glory, try to spot it at moonrise or moonset, when it's on horizon.)
June 23:
Biggest Full Moon of 2013
On June 23, the moon turns full at 7:32 a.m. EDT(1132 GMT),and just 32 minutes earlier it will arrive at its closest point to the Earth in 2013 at a distance of 221,824 miles (356,991 km), making it a so-called supermoon.Expect a large range in ocean tides (exceptionally low to exceptionally high) for the next few days.
Aug. 12:
The Perseid Meteor Shower
The annual Perseid meteor shower is
considered among the best of the annual displays thanks to its high
rates of up to 90-meteors-per-hour for a single observer, as well as its
reliability. The shower is beloved by summer campers and often
discovered by city dwellers who might be spending time in the country
under dark, starry skies.
Night sky watcher David Kingham took this photo of the Perseid meteor shower from Snowy Range in Wyoming on August 12, 2012.
This past summer, the moon was a fat waning crescent and presented a minor nuisance during the meteor shower. But in 2013, the moon will be a couple of days before first quarter and will set during the evening hours, leaving the rest of the night dark for prospective observers.
Photographer Jeff Rose captured this amazing photo of a Perseid
meteor and the bright moon just after 1 a.m. on Aug. 11 during the 2012
from Cave City, Arkansas, during the 2012 Perseid meteor shower peak.
Oct. 18:
Penumbral Eclipse of the Moon
The moon slides through the northern part of the Earth's penumbral shadow during this lunar eclipse event.
At mid-eclipse, 76 percent of the moon's diameter will be immersed in the penumbra, probably deep enough to cause a faint, yet discernible darkening of the moon's lower limb. The region of visibility includes much of Asia, Europe and Africa. The central and eastern portion of North America will get a view of the slightly darkened Hunters' Moon during the early evening hours.
Nov. 3:
Hybrid Eclipse of the Sun
This is a rather unusual solar eclipse in that, along its track, which runs for 8,450 miles (13,600 km) across the Earth's surface, the eclipse quickly morphs from annular to total; it is therefore known to astronomers as a "hybrid eclipse."
Truth be told, along most of the track, the eclipse appears as a total, with a very thin annulus (or ring) of sunlight visible near the very beginning of the track. The track of the central line of this eclipse begins in the Atlantic about 545 miles (875 km)southwest of Bermuda. So, along North America's Atlantic Coast, interested viewers (using proper viewing devices, such as pinhole projection or #14 welders glass) will only see the dark disk of the moon exiting the sun's face at sunrise.
The eclipse track will pass south of the Cape Verde Islands, then curve southeastward parallel to the African coastline. The greatest eclipse, with 100 seconds of totality and the path width reaching a maximum of just 36 miles (58 km), occurs approximately 250 miles (402 km) off the coast of Liberia. The shadow track will then sweep across central Africa, passing over sections of Gabon, Congo, Democratic Republic of the Congo, Uganda and Kenya, before ending at sunset at the Ethiopia-Somalia border.
Mid-November Through December:
Comet ISON
On Sep. 21, 2012, two amateur astronomers (Vitali Nevski of Belarus and Artyom Novichonok of Russia)used a telescope owned by the International Scientific Optical Network to discover a new comet that was christened using the acronym of the instrument used to find it: Comet ISON.
This image shows the newfound comet C/2012 (ISON) as seen by the Remanzacco Observatory in Italy.
Orbital calculations indicate that comet ISON will travel closest to the sun, less than 750,000 miles (1.2 million km) above the sun's surface, making it a true "sungrazer," on Nov. 28 (Thanksgiving Day in the United States).
The comet could eventually be bright enough to be visible in broad daylight around the time of its nearest approach to the sun. It will then travel toward Earth, passing within 40 million miles (64 million km) of our planet a month later.
Since comet ISON will become very well placed for viewing in the morning and evening sky from the Northern Hemisphere during the following weeks, it could become one of the most watched comets of all time.
December (all month):
Dazzling Venus
Venus, the brightest of all the planets, puts on a holiday show all month long, and what a spectacular one it is! Venus is the showiest it will be for all of 2013 and 2014 either in the evening or morning sky. It adorns the southwestern evening sky as much as three hours after sundown at the beginning of the month, and 1.5 hours after sundown by New Year's Eve. A lovely, crescent moon passes well above and to the right of the planeton Dec. 5, and the next night Venus will reach the pinnacle of its brilliance; Venus won’t be as bright an "evening star" again until 2021.
Dec. 13 to 14:
Geminid Meteor Shower
If there is one meteor display guaranteed to put on a very entertaining show, it is the Geminid meteor shower. Most meteor experts now place it at the top of the list, as it surpasses in brilliance and reliability even August's Perseids.
Unfortunately, in 2013, the moon will be several days before full phase and will light up the sky for much of the night, hiding many of the fainter meteors. But around 4:30 a.m. (your local time), the moon will have finally set, leaving the sky completely dark for about an hour. That will be your chance to make as many as two meteor sightings per minute, or 120 per hour!
So stargazers mark your calendars: 2013 promises to be a great year for skywatching, and if you take an impressive photo of the night sky, let us know!
