Astronomical Diary for 1999 for Maine All times and dates in Eastern Time
The Astronomical Diary for 1999 (giving times of equinoxes, solstices, an eclipse, New and Full Moon phases, and beginning/ending dates of Daylight Savings time) is tabulated below. It reports these in the time format most useful to Maine, i.e.all times are given in Eastern Time (Standard or Daylight Savings, as appropriate). Some almanacs and calendars are casual about this time change, and/or give the data in Universal Time (Greenwich Mean Time).
The lunar and solar events given below (except for the solar eclipse of August 11) do not depend on one's location on Earth. Therefore the times given are the moments (in Eastern Time) when they precisely occur. However, sunrise, sunset, moonrise and moonset do depend on location. Link to the U.S. Naval Observatory's Astronomical Applications: Data Online page to calculate these at need.
As you are sure to notice below, there is no Full Moon in February, 1999! The moon's synodic period of revolution around the Earth is approximately 29.5 days -- known as 1 lunation, when counted from one Full Moon phase to the next. Because the year begins with a Full Moon on January 1, the first two of the year just happen to both squeeze into January. February is a short month of 28 days, and thus just misses the next lunation. The next two Full Moons fall in March -- giving us two lunar doubleheaders in one year, so to speak! The year closes with a Full Moon almost exactly on the Winter Solstice, an infrequent happenstance of the two cycles, solar and lunar.

*The solar eclipse of August 11 will not be total in Maine. The Sun will rise almost fully eclipsed at about 5:30 am EDST; and the Moon will continue to move away from the Sun's disc. The eclipse ends locally about 6:30 am. Protect your eyes during observations! Sunglasses are insufficient!
