Just to let you know.
Tonight starting at 19:45 BST, the moon will start to occult the Pleiades.
Unfortunatly at this time its below our horizon and wont rise untill just after 20:00.
It probably wont be visible from Orpington untill much later.
As the occultation finishes about 21:35, we might be able to get some views of it a bit later on.
Could present a challenge for someone.
