1623 – Simon Newcomb wrote “I believe we must accord to BULLIALDUS the honor of being the first to actually observe the time of an occultation with a telescope.” His observation of a Spica reappearance on July 5,1623, observed from Paris, was made before clocks were available. The event time was computed using the relative positions of stars. This event is the first in David Herald’s list of occultation observations.
