looking out in easterly direction over the ocean,around 9.45pm,8th march 2013.sydney australia.it was sightly couldy,when all of a sudden a really large flash of lighting came down in a stright line towards the ocean,as this was happening,the lighting flash also was emitting around the shape of the ufo,at the same time.this was unbelievable to me.it was about 5miles up in the night sky so very close for me to observe.i would say that it was very big in size,say about 4to5 times bigger than any 747 .i was amazed that it was very electrical in ativity.then after a few seconds i did not see anything again like it had disapeared,this undoutly will remain in my thoughts and memory for the rest of my life.
