Loughcrew Spring Equinox 2005
Sunrise at Loughcrew, 6:25am March 23rd 2005
Due to adverse weather conditions on the 20th, 21st and 22nd of March there was no spring equinox sunrise to
illuminate the chamber of Cairn T.
The sunrise on the March 23rd looked like it might be hampered by mist,
thankfully it turned out to be a perfect sunrise to illuminate the backstone
of the chamber in Cairn T.
6:30am - The sunbeam in the chamber of Cairn T before it reaches the backstone.
6:40am - The sunbeam creeps onto the backstone of Cairn T.
6:50am - The sunbeam moves across the backstone. The dark patch at the
bottom left of the image is a shadow from part of the iron gate surround at the entrance to the cairn.
6:53am - the most impressive stage of the illumination on the backstone.
6:58am - the sunbeam moves across and down on the backstone.
7:06am - the sunbeam continues its journey across and down the backstone
7:12am - beam of equinox sunlight illuminating the bottom right corner of the backstone.
7:19am - the sunbeam near its lowest point on the backstone.
7:23am - the sunbeam just before it moves off the backstone.
The progress of the sunbeam on the backstone inside Cairn T at Loughcrew was video recorded at sunrise
on the morning of March 23rd 2005. The 50 minute video has been compressed to 1 minute 46 seconds and included in
a YouTube Video.
