Only a  Partial Lunar Eclipse will be occurring in Lawrenceville since the moon will set about half way to it.

Penumbral Eclipse beginsThe Earth’s penumbra start touching the Moon’s face. Map direction West277°

Partial Eclipse beginsPartial moon eclipse starts – moon is getting red.
Moon close to horizon, so make sure you have free sight to West-northwest.

Maximal Eclipse visible in LawrencevilleThe maximum part of the eclipse occurs when the Moon is close under the horizon. The best time to view the eclipse in Lawrenceville would be around this time.
Since the Moon is near the horizon at this time, we recommend going to a high point or finding an unobstructed area with free sight to West-northwest for the best view of the eclipse.

The scientific term for the Super Moon is “perigee moon.” The perigee moon occurs when the moon’s elliptical orbit is closest to the earth. During the night of May 5-6, the full moon reached perigee and it should have appeared 14% bigger and 30% brighter (than a full moon at apogee, farthest away).

Will you be able to notice with your eye alone that tonight’s full moon is bigger or brighter than usual? Astronomers say no, but it’ll be fun to stand outside under tonight’s full moon and know the moon is closer than it has been since March 19, 2011.

At perigee, the moon lies only 356,955 kilometers (221,802 miles) away. Later this month, on May 19, the moon will swing out to apogee – its farthest point for the month – at 406,448 kilometers (252,555 miles) distant.

Even the proximity of full moon with perigee in today’s moon isn’t all that rare. The extra-close moon in all of these years – 2011, 2012, 2013, 2014 and 2015 – finds the full moon taking place within an hour or so of lunar perigee. More often than not, the closest perigee of the year comes on the day that the full moon and perigee coincide.

How often does the full moon coincide with perigee? Closest full moons recur in cycles of 14 lunar (synodic) months, because 14 lunar months almost exactly equal 15 returns to perigee. A lunar month refers to the time period between successive full moons, a mean period of 29.53059 days. An anomalistic month refers to successive returns to perigee, a period of 27.55455 days. Hence:

14 x 29.53059 days = 413.428 days
15 x 27.55455 days = 413.318 days

This time period is equal to about 1 year, 1 month, and 18 days. The full moon and perigee will realign again on June 23, 2013, because the 14th full moon after today’s full moon will fall on that date.

Moon closest to Earth


Year Date Distance
2011 March 19 356,575 km
2012 May 6 356,955 km
2013 June 23 356,991 km
2014 August 10 356,896 km
2015 September 28 356,877 km


Looking further into the future, the perigee full moon on November 14, 2016 (356,509 km) will even be closer than the one on March 19, 2011 (356,575 km). The perigee full moon will come closer than 356,500 kilometers for the first time in the 21st century on November 25, 2034 (356,446 km). The closest moon of the 21st century will fall on December 6, 2052 (356,421 km).
