I was walking my dog around the block and looking at the big dipper when the objects appeared to the left of the big dipper. at first there were 3 dots of light in a row equally spaced and travelling in a straight line just below the dipper and travelling faster than any high altitude planes and the lights were not blinking. there was no sound. they appeared like a satellite does except they travelled a little faster but on the same course. after the first 3 appeared , a small space occurred then a group of 5-6 lights appeared to follow the first 3 . they were grouped closer to each other. after this group came a smaller group of 4 and then 3 lights came after the other groups ahead all travelling the same speed and the same path. again i noticed no sound or erratic behavior of these lights. when the last 3 objects which were spaced evenly apart from each other passed,no others were observed behind the line.
