At times for about 1 minute bright green with hints of red. Bright enough to blot out all but the brightest stars. (Also seen from within the brightest lit areas of McMurdo Station.)

            14:30 to 15:30 Extremely bright rays and arcs over most of the sky N to S. Often obscured the brightest stars. At one time there were four curtain shaped arcs running N to S covering of the sky. Observed for an hour and then got cold!
                (S77.8 E166.7) - Arrival Heights, Ross Island, Antarctica
            14:45 No sign of aurora, not even on horizon.
                (S45.8 E169.3) - Edievale, West Otago, New Zealand

                (S77.9 E166.8) - Scott Base, Antarctica

Aug 20 11:00 to 11:30 Pale white, very wide (perhaps 20), folding bands directly overhead and to the eastern horizon. Possibly also in west but swamped by moonlight. Often brighter than most stars. Bands grew into large, more intense patches at times. Several minutes between maximum intensities. Both bands peaked at about the same time.
                (S77.9 E166.8) - Scott Base, Antarctica

Aug 21 approx 10:00 Green glow through light cloud.
                (S46.4 E169.8) - Otekura, South Otago, New Zealand

Aug 23 14:00 Very bright green arc. Dark below arc to 5. Top of arc at 15 elev.
                (S45.9 E170.5) - Dunedin, New Zealand

Aug 31 07:45 Aware that sky was lighting up in S. Reached up past False Cross, elev 10. It was quite intense with traces of crimson red in it.
            08:30 Sport lights turned off. Bright, white glow still had traces of red.
                (S45.1 E171.0) - Oamaru, North Otago, New Zealand
            09:40 to 09:50 Definite corona directly overhead and NW to S. At times brighter than the brightest stars. Slow moving spokes. Hint of green. Folding rayed band lower in E.
                (S77.9 E166.8) - Scott Base - McMurdo road, Antarctica
            10:00 Glow still active.
                (S45.1 E171.0) - Oamaru, North Otago, New Zealand
            11:00 Mostly rays, started behind Mts Erebus and Terror.
            12:00 to 14:30 Got brighter and began to move forward (higher) from Erebus. Again lots of rays but well consolidated and undulating arcs as well. They remained like this, overhead and towards the east.
            14:15 A nice grand finale. Very bright, twisting arcs moving quickly across the sky.
