Hi Nik,
I did indeed observe one of these events well over ten years ago, maybe twenty. I'd been in the pub with my dad having a drink and as I was aware this was happening we made a point of observing it with my 8.75" Dobsonian when we got back to my house. There really were no moons visible - nothing to do with having a skin full. A most extraordinary sight.
I was out at about half six last night and was surprised to see only one moon. I did see two appear a bit later but had no idea if the missing moons were transiting, occulted or eclipsed. I couldn't see any shadow transits.
Cheers and clear skies.
Dave
