Geocentric closest approach at 2019/06/11 06:00:40 UTC

J2000 position of star is 18:54:40.3 -18:38:31
Equinox of date position of star is 18:55:48.6 -18:36:58
Stellar brightness G=16.1, use SENSEUP=128
Star is 99 degrees from the moon. Moon is 61% illuminated.
TNO apparent brightness V=22.5

[RECON map]
TNO is 24.3 AU from the Sun and 23.4 AU from the Earth.
The TNO is moving 21.0 km/sec on the sky relative to the star, or, 4.5 arcsec/hr.
The 1-sigma error in the time of the event is 1375 seconds.
The 1-sigma cross-track error in the shadow position is 5462 km.
The sky-plane scale is 16965.3 km/arcsec.

The TNO has an absolute magnitude Hv=8.6
Diameter=114.8 km assuming a 5% albedo -- 5.5 sec chord
Diameter=46.9 km assuming a 30% albedo -- 2.2 sec chord
Dynamical classification is CENTAURR
