Looking for diversion from the wtaf-ness of the news? I have a stargazing challenge for you👇
Just completed it myself on Portobello Beach: got overly excited by the beauty of it all & accidentally accosted a group of French photo-taking tourists to tell them all about it
"C'est vraiment Jupiter?"🤩 🔭
I have a Wolf supermoon stargazing challenge for you tonight (Jan3rd, weather Gods willing). Raise your arm to the moon to find Jupiter which is ~2-fingers below it to the right. The Gemini twins, Castor and Pollux are ~3-fingers to the left.

This is your last #supermoon until Nov - enjoy! 🔭🧪
