RECON: TNO occultation with 01KG76

Event between 01KG76 and star GA0660:15570177 with event index number of 270638

Geocentric closest approach at 2020/06/18 04:33:24 UTC

J2000 position of star is 17:36:33.8 -23:01:05
Equinox of date position of star is 17:37:47.3 -23:01:46
Stellar brightness G=16.3, use SENSEUP=128
Star is 147 degrees from the moon. Moon is 10% illuminated.
TNO apparent brightness V=26.9

[RECON map]
TNO is 49.9 AU from the Sun and 48.9 AU from the Earth.
The TNO is moving 25.3 km/sec on the sky relative to the star, or, 2.6 arcsec/hr.
The 1-sigma error in the time of the event is 1146 seconds.
The 1-sigma cross-track error in the shadow position is 5080 km.
The sky-plane scale is 35446.7 km/arcsec.

The TNO has an absolute magnitude Hv=10.0
Diameter=311.9 km assuming a 5% albedo -- 2.4 sec chord
Diameter=127.3 km assuming a 30% albedo -- 1.0 sec chord
Dynamical classification is 9:4EEEEE
