Natural Satellites Service. Special ephemerides
Mutual occultations and eclipses
of the major satellites of Uranus
in 2006-2010
by N.Emelyanov
Topics
- We present the ephemerides and circumstances
of the mutual occultations and eclipses of the
major Uranian satellites in 2006-2010.
-
Photometric observations of these events is an effective tool for
obtaining new astrometric data that can help in the refinement
of the theory of satellite motion.
-
The mutual occultations and eclipses of the major satellites
of Uranus occur at epochs of about 4 years in duration.
These epochs follow each 43 years.
-
In 2006-2010 about 190 mutual occultations and eclipses
will occur. Maximum of events falls at 2007.
-
Not only predicted events but also
apparent encounters of satellites (annulating events) must be observed
because
these encounters predicted with a theory of a limited precision
may be real mutual occultations or eclipses.
-
The ephemerides of the mutual occultations and eclipses of the major satellites
of Uranus in 2006-2010 are presented in four tables according to four
periods of visibility of Uranus.
