  I saw a beautiful large corona around the moon last night in West Sussex. Unfortunately my camera was not good enough to capture a photo. Could some one please explain how and when these occur? Is it a common or rare event? Thank you Nicky

  Have a look here for explanations and examples of all types of optical phenomena: http://www.atoptics.co.uk/
  Corona appears under “water droplet” section: http://www.atoptics.co.uk/droplets/corona.htm whilst halos are here: http://www.atoptics.co.uk/halosim.htm

  I see that a lunar halo was photographed in Colne, Lancashire last night. Here’s the BBC Weather tweet:

  And another lunar-halo photo, this time from Selsey, West Sussex. Also aurora and green-flash photos on the same page:
