April 5, Easter Sunday, a day after full moon, and spring finally seemed to have arrived. Hail and heavy winds halted and the thick cloud cover dispersed. Blue skies and sunshine at last.
Arriving at the Grianán this time before the moon, I was hoping to see the growth of the beam inside the monument. A long dusk still illuminated the sky for an hour and a half after sunset and about fifteen minutes later, around 9.35 pm the moon rose from behind hills and hazy clouds. But as already worryingly noticed on my crazy moon location finder (Stellarium), the April rising had taken a generous leap to the south.
My worries were confirmed as the moon rose higher and higher but its beam never even made it for moment through the gate and inside the monument. At it furthest extent the beam covered about ¾ of the northern wall of the entrance.
This seasonal shift of the moon’s point of rising to the south will continue throughout May, June and July, leaving me in suspense over the extension of the beam inside the Grianán until August, by which time the moon will return to a eastern and hopefully beam producing position.
