Thiruvananthapuram: Barely 24 hours away from the partial lunar eclipse on New Year’s Eve, city residents witnessed another rare celestial event on Wednesday. A large bright halo hung around the moon, with a colourful outer ring on the fringes.
K. Santhosh, Director, Meteorological Centre, said the phenomenon was caused by a rare confluence of several factors.
“The absence of clouds in the lower atmosphere and the reflection and refraction of light from ice crystals formed in the upper atmosphere clouds at a height of six to 10 km are responsible for the event.
“The colourful outer halo is the result of dispersion of light into different colours.”
People came out of their houses and offices to witness the sight.
Many rang up media offices hoping to gather information on the event.
