2012 stellar Occultations by TNOs Campaigns

More information about the predictions can be found in Bruno Sicardy's web page and in Assafin et al. 2010 (for Pluto system predictions) and Assafin et al. 2012 (for the TNO preditions). Please, do references about the predictions to Sicardy's web page and/or Assafin et al. 2010 and 2012 paper.


- 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.
