Geocentric closest approach at 2019/03/18 08:56:44 UTC

J2000 position of star is 15:47:14.1 -16:32:31
Equinox of date position of star is 15:48:18.2 -16:35:57
Stellar brightness G=14.7, use SENSEUP=128
Star is 99 degrees from the moon. Moon is 89% illuminated.
TNO apparent brightness V=22.4

[RECON map]
TNO is 42.1 AU from the Sun and 41.6 AU from the Earth.
The TNO is moving 9.5 km/sec on the sky relative to the star, or, 1.1 arcsec/hr.
The 1-sigma error in the time of the event is 658 seconds.
The 1-sigma cross-track error in the shadow position is 5971 km.
The sky-plane scale is 30146.7 km/arcsec.

The TNO has an absolute magnitude Hv=6.0
Diameter=375.0 km assuming a 5% albedo -- 39.5 sec chord
Diameter=153.1 km assuming a 30% albedo -- 16.1 sec chord
Dynamical classification is CLASSICAL
