Bright light came in NNE, very fast and stop above Chace Ranges - Mt Havlock region. The light seemingly disappeared into or behind the Chance Range side. We were camped at the shearers/crutching sheds between the druid and chace ranges near the dry river bed. Light appeared after aprox 2 mins, which was bright enough at night for us to read a map clear. A brilliant white/blue light. No noise, including wildlife. It seemed to hover above the pipeline road for a further 4 or so mins and then went racing off in the same direction it came from.
