Well ... technically Houghy did in another post and I raced back here to let people know that I'd found my answer... before people went to the trouble of trying to figure out what I'd seen
Yes, I saw it too :-) I was out at Murrumbateman, had just finished setting up the scope and was relaxing in a chair admiring the view (as one does), and saw the thing go over. Was very bright!
When it went past sirius it was clearly a more yellow colour than sirius due to reflected sunlight. Made quite a show.
Then later on I was outside again when the iridium flare happened. Boy, that one caught me off guard! Took a few moments to figure out what it was, they're very bright!
