Geocentric closest approach at 2021/06/03 06:59:04 UTC

J2000 position of star is 17:51:32.9 -24:14:40
Equinox of date position of star is 17:52:51.5 -24:14:55
Stellar brightness G=16.5, use SENSEUP=128 with the MallinCam and and exposure time of 2 seconds with the QHY174 camera.
Star is 86 degrees from the moon. Moon is 40% illuminated.
TNO apparent brightness V=22.4

[RECON map]
TNO is 32.1 AU from the Sun and 31.1 AU from the Earth.
The TNO is moving 22.5 km/sec on the sky relative to the star, or, 3.6 arcsec/hr.
