Monday, December 12, 2016 was wet and rainy and made conditions both in the Temple and on the Hill difficult. However in spite of windy sleeting rains both the Deepams in the Temple and on the Hill were lit at dusk (approximately 6 p.m.) that evening.
Below are photographs of both Deepams. The Deepam in the Temple was lit first and as soon as a lookout on the Hill was notified that the Temple Deepam is afire, then the Deepam on Arunachala is set alight.
