Three orange spheres in trangular formation came and went.We were sitting outside at about 23:00 hours, in boronia (Melbourne Australia). Three orange balls appeared in the sky when we were facing North East, at about 45 degrees. At first the three phenomenon appeared to form an arrowhead type shape, then as the three of us watched, the three balls moved into a perfectly equalateral triangle and kept this shape for the duration, until the botton left first dissappeared, then top soon after. The last phenomenon then stayed visible for another 30 seconds or so, then finalley faded away. As they dissapeared, they looked to be almost heading further away from us, at the exact same tragectory as they originalley came. At first they looked as if they were coming towards us, by the look that they were getting bigger as time passed. The best description i can come up with is that they looked like balls of fire, yet the transfer of shape, and the holding of an equalateral triangle for at least a minute and a half seems to put forward the idea that these were more than just atmospheric anomolies.
