SuperMoon over Arlington Heights about 4:00 a.m. Sunday, May 5, 2012, just over four hours after perigee coincided with a full Moon at 11:35 p.m. Saturday, May 5, 2012.

A perigee is the point in orbit that an object makes its closest approach to earth. The Moon is full while in perigee about once every 412 days. The perigee doesn’t always happen at the same time as a full Moon. A supermoon, is the coincidence of a Full Moon (or a New Moon) with perigee. The actual time of the coincidence was at 11:35 p.m. Saturday, May 5, 2012.

The SuperMoon of May 5, 2012 (11:35 p.m. CDT) was 14% bigger and 30% brighter than regular Full Moon phases. The moon was 356,953 kilometers or 221,800 miles away.

On May 19, 2012 the moon is in apogee, which is the furthest approach in the period of the orbit. At apogee on May 19, the Moon is 406,450 kilometers or 252,556 miles away.

Next year there is a SuperMoon on June 23, 2012.

The full Moon will be up to 14% larger and 30% brighter than others during the year. The reason for this phenomenon is that the Moon becomes full on its closest approach to Earth on Saturday May 5, 2012, also known as the perigee full Moon.

A “supermoon” is the coincidence of a full moon (or a new moon) with the closest approach the Moon makes to the Earth on its elliptical orbit, or perigee, leading to the technical name for a supermoon of the perigee-syzygy of the Earth-Moon-Sun system. The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions. However, the evidence of such a link is widely held to be unconvincing.

Full Moons are traditionally associated with temporal insomnia, insanity (hence the terms lunacy and lunatic) and various “magical phenomena” such as lycanthropy. Psychologists, however, have found that there is no strong evidence for effects on human behavior around the time of a full moon.

Arlington Heights firefighters fighting an interior attack for a fire apparently caused by a lightning strike on North Drury Lane about 2:30 a.m. Friday, May 4, 2012.

Firefighters on the driveway prepare to go to the roof of a duplex to ventilate the roof and fight the fire with a line on the roof.

Arlington Heights firefighters put a quick stop on a roof and attic fire that was apparently caused by a lightning strike about 2:30 a.m. Friday. Did you hear the thunder? Even though the rain and thunderstorms were ending, an intense, bright flash and cloud-to-ground lightning strike hit the area and apparently caused serious house fire. The heaviest thunderstorms trained south of the northwest suburbs but affected Schaumburg, Hoffman Estates, Morton Grove, Lincolnwood, Harwood Heights and other suburbs south of Arlington Heights were hit with hail, heavy rain, high winds and intense lightning.

The Arlington Heights lightning strike was nature’s encore for our area, which only experienced moderate rain and no severe thunderstorms. The stormy weather was almost finished when the duplex house on Drury Lane was hit, and seven residents had to evacuate their homes. See the report on the fire, including video, at The Cardinal Duplex House Fire After Lightning Strike on Drury Ln, Arlington Heights; 7 Residents Escape …
