A Territory woman says strange lights spotted flying over Borroloola late last year had also been seen in the area 20 years ago.

Robyn Doddrell, 55, who now lives in Humpty Doo, was living and working in Borroloola in February 1989 when she said the bright orange lights descended on the town.

Last week the Northern Territory News revealed that Borroloola woman Cheryl Keighran had been followed for about 25km by a bright light in the sky that appeared to turn into an orange ball. Now Ms Doddrell has revealed a similar occurrence two decades earlier.

She said she was at home when the light appeared. ''It was glowing right on the outskirts of town. ''It was just amazing.''

Some observers believe the lights seen last year may have been Min Min lights -- an unusual light formation seen numerous times in the outback -- but Ms Doddrell said the lights seemed to be sucking the power out of the town.

''The power was going up and down as the light went up and down,'' she said. ''It was no Min Min light. ''It happened about six or seven times on that night but I never saw another thing. ''I can remember it as vividly as if it was yesterday. I stood at that window for at least half an hour afterwards. ''That actually happened to me -- and I don't drink or smoke.''
