Whilst up early to photograph Venus and the crescent Moon on the 26th June 2022 at Dartford top road, member Jim Burchell also saw some Noctilucent Cloud too around 3am!  The 1st Noctilucent Cloud (NLC) sighting for CMHASD NLC season 2022. 

Jim sent out an alert via Whatsapp to members which Diane Clarke picked up and so too managed to photograph the NLC that morning from North Kent.

Rainbows – not 1, not 2 but 3! captured by Martin Crow

Oh my word, what a fortunate man member Martin Crow was last evening whilst out Kayaking on the river near Burnham on Crouch in Essex.  Martin got to witness something very rare and absolutely stunning; 3 rainbows together!!!  Two rainbows are often seen by people but 3 rainbows or the beginnings of a 3rd is a rare sight to see. 

Luckily Martin captured this special event on his phone, see below and member Honor Wheeler explained the 3rd rainbow  ”It’s a reflection of the main rainbow from the water reflecting back into the sky.  A reflection bow. Super capture lucky you”.

Whilst the points awarding is somewhat ambiguous I’ll be looking for the following…

  • Technically a good image (in focus)
  • Well composed 
  • Other points of interest (foreground or background)
  • A good story – if you have a story of how you took the image it can’t hurt!

Entry criteria:

  • You can only enter if you are a paid up member (any tier of membership)
  • Entries must be to – feel free to post them on what’s app as well!
