Meteor like object moving slowly eventually breaking apart leaving a blue streak.This object appeared to be a VERY LARGE meteor but it was wider and moved very slowly in an upward direction. I asked my husband to join me outside and at that time it broke off in half and the top part continued on for another 10 seconds or so eventually dissapating. A blue "trail" could then be seen in the dark sky. What was it?????((Vandenberg rocket launch. PD))
