Abstract:
Occultations of stars brighter than 15m by largest trans-Neptunian
objects (TNOs) are predicted. Search was performed using the following
catalogues: Hipparcos (Cat. I/239; Tycho2 (Cat. I/259) with
coordinates of 2838666 stars taken from UCAC2 (Herald, 2003); UCAC2
(Zacharias et al., 2003, Cat. I/289) with 16356096 stars between
12.00 and 14.99mag to the north from -45° declination. Predictions
were made for 17 largest numbered transneptunian asteroids and 4 known
binary Kuiper Belt objects. 67 events occuring at solar elongation of
30° and more are selected. Observations of these occultations by
all available means are extremely important since they can give unique
information about the size of TNOs and improve their orbits
dramatically.

Note (1): Diameter is calculated from H0 by the formula
log(D)=3.52-0.2*H0
supposing a single body. For binary asteroids with two bodies of
the same size and albedo diameter of each component will be 0.71*D.
Note (2): Central event duration for estimated single body diameter.
