Atlantis on the move!  This view of shock-wave condensation collars backlit by the Sun occurred during the launch of the Space Shuttle Atlantis on September 8, 2000.  The primary effect is created by the forward fuselage of Atlantis, and secondary effects can be seen on the solid rocket booster (SRB) forward skirt, Shuttle vertical stabilizer and wing trailing edge, and behind the Space Shuttle Main Engines (SSME).  T minus 70 hours...and counting...Light the fire!
