Geocentric closest approach at 2020/04/16 04:58:12 UTC

J2000 position of star is 13:39:08.7 -12:29:15
Equinox of date position of star is 13:40:08.9 -12:34:57
Stellar brightness G=14.0, use SENSEUP=64
Star is 103 degrees from the moon. Moon is 38% illuminated.
TNO apparent brightness V=24.8

[RECON map]
TNO is 46.1 AU from the Sun and 45.1 AU from the Earth.
The TNO is moving 25.8 km/sec on the sky relative to the star, or, 2.8 arcsec/hr.
The 1-sigma error in the time of the event is 326 seconds.
The 1-sigma cross-track error in the shadow position is 5811 km.
The sky-plane scale is 32704.4 km/arcsec.

The TNO has an absolute magnitude Hv=8.2
Diameter=140.6 km assuming a 5% albedo -- 5.4 sec chord
Diameter=57.4 km assuming a 30% albedo -- 2.2 sec chord
Dynamical classification is 3:2E
