I was opening my house front door leading onto the porch which over lookef my property's paddock and I instantly saw it above the treeline between 30-50 degrees in the sky, night time. lasted for about 5 seceonds. The bright white orb quickly moved from right to left to right, pausing for half a second in each direction then flew away at a speed I've never witnessed. Incredibly fast. I also saw various other similar objects at a further distance higher in the sky (this was at night about 10 minutes after lasting for an hour) move erratically and in organised and exact triangular formation. Clouds left streaks in the sky in a pattern never seen before. Clouds also left and moved extremely quickly (like close encounters of the third kind) when the ufo disappeared over the horizon.I felt in awe. Static. Emotional. Scared but obsessed. The most amazing feeling.
