Natural Satellites Service. Special ephemerides
Mutual occultations and eclipses
of the major satellites of Uranus
- 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
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.
