It steadily increased in brightness up to UMa. It seemed to decrease in brightness in the final few seconds that I saw it (I lost contact due to some obstruction in my field of view). But whether this was due to the disappearance effect or due to the obstructions (and some clouds) getting in my way I cannot re-construct. Half an hour ago (at 20:56:35, 1-AUG-06) I observed what looked like the beginning of a flare of L5 (which passed from Arctures to UMa) but once again clouds got into my way.
