The Minor Planet Center is introducing a new format for ephemerides on
these circulars, as shown above. Ephemeris data is supplied for "today"
(i.e., the date of the circular) and for dates +/- 1, 7, 15 and 30 days from
"today", allowing an observer to see in a concise form the potential for
future observations and indicating whether searches for recent pre-discovery
images are worthwhile.
