From CBS News:
Solstice, the official start of summer, is the longest day of the year, and this year it also brings a rare event in the night's sky. Those who look up at the moon tonight will see what's called the "strawberry moon," the nickname for June's full moon, which happens to coincide this year with the summer solstice.It was a beautiful summer night at the lake.
...For summer stargazers out there, it's the first chance to see a full moon on the summer solstice in nearly half a century. According to AccuWeather.com, the last time these two phenomena coincided was back in 1967, and it won't happen again until 2062.
