Just a heads up note to say there is a line of severe storms 200km South of Brisbane moving north-east and there is good potential to capture lightening sprites from these storms for people located in SE QLD. Given that it is partly clear, expect to seem them around 20-30 degrees up in the South to south-east. Ideal cameras is sensitive BW video cameras + wide angle lens. As I have shown a modified DSLR + fast wide angle lens will capture them (try sequences of 10sec exposures @ ISO1600).
Have a look at the Grafton Radar:
