Geocentric closest approach at 2019/03/29 07:11:03 UTC
J2000 position of star is 05:27:54.8 +30:04:15
Equinox of date position of star is 05:29:05.6 +30:05:06
Stellar brightness G=12.1,
use SENSEUP=16
Star is 151 degrees from the moon.
Moon is 39% illuminated.
TNO apparent brightness V=21.1
TNO is 41.3 AU from the Sun
and 41.5 AU from the Earth.
The TNO is moving 12.3
km/sec on the sky relative to the star, or,
1.5 arcsec/hr.
The 1-sigma error in the time of the event is 802 seconds.
The 1-sigma cross-track error in the shadow position is
4607 km.
The TNO has an absolute magnitude Hv=4.8
Diameter=660.7 km assuming a 5% albedo -- 53.8 sec chord
Diameter=269.7 km assuming a 30% albedo -- 22.0 sec chord
Dynamical classification is CLASSICAL
