The largest, brightest full moon of the year will rise in the sky this weekend, a phenomenon that ranks as one of the biggest celestial events of the year in what astronomers call a “perigee full moon.”
Tides will be stronger than usual along the shores, and watch for the crazy people out around the bars at night.
The summer solstice, the longest day of the year and the official first day of the summer season, came Friday, and the full moon starts Saturday night.
“The visual effect is to make this the lowest-down full moon of 2013,” astronomer Bob Berman said in a news release from Slooh Space Camera. “And since lower moons tend to be orange, yellow or amber, shining as they do through more than twice as much reddening air and moisture, this lunar experience should give us a true ‘honey moon’ all night long. Moreover, lower moons look larger, thanks to the famous ‘moon illusion.’ This second moon-enhancing effect will be more visually obvious than its actual size increase.”
According to the definition used by Farmer’s Almanac, there will be three supermoons this year, including one that took place on May 25 and another that’s due on July 22. Neither of those quite matches up to this weekend’s moon — and technically speaking, this weekend’s supermoon is slightly less super than last year’s.
