Mr Flum pointed out a sundog while we were on the bus just after 3pm; we then realised that in fact it was a 22° halo in cirrostratus cloud. Photos from the bus were poor but it remained well after we had alighted (the location on the map). This is tweeked (gamma and brightness reduced) as I do not have a polarising filter on my point-and-shoot camera. Note that the gap between the sun and the halo is darker than the sky outside the ring.
Earlier we had been to the Botanics and thought we'd look in on the Titan Arum, which is in flower for the second time, having flowered, causing great excitement, just two years ago. Expecting it to be well past its best, we found, as the extra shows, that it is still in reasonable condition.
