Name our Storms
The Met Office is currently looking for people to suggest up to 5 names for storms...
It would be great if thousands all suggested the same 5 names (in alphabetical order as that's how storm names appear):
BigOil, BP, Equinor, Exxon, Shell.

In the foreground, a brass Orrery with lots of cogs and model planets showing. The orrery sits on a cloth with constellations and stars marked. Behind the orrery are two people, the closer wearing glasses, and further one who is too out-of-focus to see clearly.
Excellent conversations on Friday with guest scientist Steve and his beautiful #Orrery.
#QuestionOfTheMonth - How did they know that the planets moved like the Orrery?
