comma after introductory elliptic clause [conjunction]: While..., he

[Setwale_Charm]

Heya all!
Just to be certain: does one need to put a comma in a sentence like this: While on the Moon (,) Alan played golf?

Thank you.

No, commas are entirely optional after practically any time or place phrase, of any length. A comma might make it easier to read, or might better reflect the pronunciation, but usually both intonations are possible and natural.

Thanks a lot, entangledbank!
