“The moonbow framed the lightning nicely–a rare and beautiful coincidence,” says Glendinning.
Everyone knows what lightning is. But a moonbow? It’s the same as a rainbow with the Moon playing the role of Sun. Raindrops falling in the Northumberland night caught the rays of the waxing full Moon and spread them into a fan of prismatic color.
Glendinning’s exposure revealed something even more rare: a secondary moonbow. It’s the faint ‘bow arciing above the brighter primary. Primary rainbows are caused by single reflections inside raindrops; secondary bows are caused by double reflections. Watch for them both this weekend.
