Hi Jari,

(ASCII lacks a "not-equals-to" sign.) Ask for a conjunction of the
Moon with just about anything, and Guide will find one within
about 14 days (half a lunar month) of the current time. But there
is no guarantee that an occultation will occur on that date. In
some cases, Guide will sit and spin for a while, finding conjunction
after conjunction at roughly 27.3-day intervals, but not finding an
occultation.
