At 00.10LT last night i observed a selection of stunning atmospheric phenomena around the waxing gibbous moon which at the time was 23* above the SW horizon. Surrounding the moon was a 60* wide 5* thick very bright Halo that was almost a complete 360* except its southern section was below the horizon. The halo had a bright red fringe on the inside while its outer edge was a lovely blue/white colour. Placed on the Halo at 30* to the east and west of the moon i saw to very bright moondogs (Paraselena) that looked like two bright white patches of light. As i watched one would dim in real time and the other would brighten then the reverse would happen. At one stage the east dog brightened, became strongly condensed, elongated horizontaly and grew a tail which is the first time i have seen a Lunar Parhelic Circle!!!! As if this was not enough i could see a stunningly bright Upprer Tangent Arc with 'horns' that curved upwards (another first). Connecting this to the moon was a 30* tall lunar pillar. All of these phenomena where visible at the same time and combined with the colours it was a sight to behold!!! Pity i had no camera.
