If there have been no recent updates try The German comet group page or Seiichi Yoshida's page for information or the Liga Iberoamericana de Astronomia for observations.<\/p>\n
Planning aids and information for forthcoming comets <\/p>\n
An explanation of the information in the ephemerides is given here. The following magnitude parameters, last updated 2015 February 1, are used in the ephemerides, but note that ephemerides are not updated every time the magnitude parameters are. <\/p>\n
The following lists [updated 2015 February 1] give the ephemeris details, including the approximate current magnitude and local visibility for all the comets in the CBAT list for the UK, the equator and 40 south. CCD observers should try and observe any comets that have not recently been observed according to the CBAT but which are expected to be within range of their equipment. Negative observations are also useful. <\/p>\n
For positions of newly discovered comets see the NEO confirmation page . You can also generate your own ephemerides and elements at the CBAT Minor Planet and Comet Ephemeris Service web page. The elements and ephemerides from the JPL Small-Body Database Browser give estimates of the errors, which are often far larger than might be thought from the accuracy of the elements given by the CBAT. Seiichi Yoshida has pages for currently visible comets, which include finder charts. Seiichi also has a comet rendezvous page, which lists conjunctions between comets, variable stars and nebulae and a comet recovery page, which lists periodic comets not yet recovered at the present return. The T3 project aims to discover comets amongst the population of asteroids influenced by Jupiter. Following a hack at the MPC, MPECs etc are now available at this site <\/p>\n
