It’s not often I can stake my claim to a first, but here is double one. First amateur to capture a Centaur (that’s an asteroid between Saturn and Neptune) occulting a star and also the first amateur to record the rings around an asteroid!
Charliko is the only known asteroid to have rings. They were discovered last year by a team of professional astronomers lead by Prof Bruno Sicardy who is a great friend to the amateur and whom provides us with great predictions so that we can help provide him data. This event was well attended by the Australian Occultation faithful and I recorded in somewhat difficult circumstances the event. Unfortunately I was the only person to capture it – the more ‘chords’ the better the scientific payload but Bruno assures me that the data will be added to the original observations and will significantly improve the positional data that we know about the rock.
And that is great news, because with better predictions, we can make even better observations in the future. Sweet.
