**Signal Observability at Hyper Light Velocity**Abstract—In [1] an observer at rest and perpendicular to moving source will detect a difference in the time of arrival of the initial τ0 and final τ' waves as τ' > τ0 a transverse relative time shift. The position of the observer in [1] for source velocities near the speed of light has the disadvantage of having to wait a long time to detect τ'. The observer cannot detect τ' for velocities equal to or greater than the speed of light. This work shows that moving the observer to a strategic position downstream from the τ' signal has the advantage of introducing observability of τ'. The transverse relative time shift formulas are derived for the stationary observer perpendicular to and also on the path axis for velocities less than and much greater than c. Also, a method to calculate transverse relative length is proposed.
