unusual lights over oceansobserved from 39000ft over mid atlantic ocean, initially from W2720.0 on the north atlantic track system: ball shaped white light light observed in approx direction of the sky over iceland.very high up, possibly low earth orbit. light appeared to travel approx in our direction, dipping slightly, got much brighter and then looped away northeastward growing dimmer. this happened in the same place 3 times. on the second occasion a small very fast light appeared to 'chase' the first brighter one as it was receeding. event times were approx. 0701z, 0711z, 0721z. At its brightest the light was much brighter than the background stars, and of similar intensity to a bright shooting star.it was a dark moonless night with many shooting stars, but they dont move in eliptical paths !. Also around the same time another object was seen to track south east ward from a position abeam left, to infront overhead, to right side horizon. its path was only visible as it pulsed light, one short quick pulse, one slightly longer one. this occurred 3 times (that I saw) each pair of pulses showed the objects track to be consistent with the last.Its, aprox. track was southeast.i believe what i observed is consistent with a test of a space based weapons system. I have never seen anything unusual in 20 yrs of professional aviation, and 10 yrs on the N. Atlantic.
