                (S40.9 E175.5) - near Masterton, New Zealand
            10:46 to 12:12 Very bright glow on the horizon and then quickly developed to fill half the sky. Rays started and moved left to right across the sky reaching an elev of 45░ until peak of activity at 11:35. the sky would flush red and the base greenish blue. Rays faded at 11:16 but the aurora was still a deep red arc. At 11:35 the red colour faded. Rays continued until 12:01 and sky darkened although there was still a light glow.
                (S42.3 E147.2) - Longford, Tasmania, Australia

            11:05 to 11:45 Well-defined bright green to yellowish-white arc 2░ to 3░ wide SSE to SW to 10░ elev persisted throughout observing period. Patches each end brightening and fading within 1 minute period. Three relatively persistent patches of red at SSE leve 40░, SW elev 50░ and W elev 30░. Rays 20░ (bottom) to 50░ (top) red in upper parts brightening and rising and then subsiding over 1 to 2 minute period. Display expanded to the W for 2 or 3 minutes around 11:25. Around 11:30 a singlebroad (4░ to 5░ wide) just E of S extended to elev 80░ for several minutes. During the 40 minutes there werenumerous changes occurring in random positions along and above the arc and some moderate flaming. A few unusual dark patches along the draperies. During about the first ╝ hour the sharply defined lower edge of the arc rose from a few degrees elev to 7░ or 8░ in centre (just W of S) and then became diffuse after display peaked. At 11:40 in only about 2 minutes it subsided to a bright green homogeneous glow to 45░ elev with no further signs of activity. IBC 3.
