Daily  comet  ephemerides  for  the  period:  Monday, 1992 Apr. 20 - 27, 0 h UT
(Universal  Time).  Due  to  e-mail  problems the posting of the five different
ephemerides  has  to  be  made  on  three days. Only every fifth issue of these
different ephemerides detailed explanations are given alternately!
