2012 stellar Occultations by TNOs Campaigns

Here you find predictions to selected stellar occultations by TNOs, that are under campaign. We will do our best to update the prediction maps, so be alert for changes in this page (last modification on 14/February/2012). If you can observe (or know who can) any of this occultations, please contact us (felipe.ribas-at-obspm.fr).

More information about the predictions can be found in Bruno Sicardy's web page and in Assafin et al. 2010.  Please, do references about the predictions to Sicardy's web page and/or Assafin et al. 2010 paper.


Informations about the maps:
- The strait and continue lines are the shadow limits considering the estimated radius;
- Each red dot is spaced by one minute, the nominal occultation time is to the big red dot (that is the geocentric closest approach);
- For Pluto and  Charon, the error is about 800km, and for the other TNOs it can be as big as 3000km.
- The star R* and K* are the R and K magnitudes, normalized to a body moving at 20km/s.

- The body offset is at the upper left corner.
- Be careful, the dates are from the moment of the event in Universal Time, the night of the event may begin at the date before.
