Details:
Last night a very rare and vivid Lunar Halo appeared around the moon ahead of a weather front which was moving in of the Atlantic onto northwestern Coast of Ireland.
With a full moon and the right condations rare vivid moon dogs appeared either side of the moon and a upper tangent arc.
This is the first time I have witnessed all 3 here in Ireland over they years. Lunar halos are normal to get in Ireland but all 3 is very rare and take the right conditions for it to occur.
Halos around the sun or moon are caused by high, thin cirrus clouds drifting high above your head. Tiny ice crystals in Earth's atmosphere create the halos. They do it by refracting and reflecting the light. Lunar halos are signs that storms or bad weather is nearby.
I captured this before midnight on Monday the 24th of September 2018.
Location Ballyshannon, Donegal, Ireland.
