Occultation event with (5476) Mulius, event index number 4983
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/02 01:29:19 UTC
J2000 position of star is 05:50:41.7 +08:17:03
Equinox of date position of star is 05:52:09.7 +08:17:24
Star is 82 degrees from the moon. Moon is 41% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=15.9
Use an exposure time of 0.50 seconds with the standard RECON-QHY system.
SNR of 4.2 per integration for unocculted signal
Expected flux drop is 58% with SNR of 2.4 for the occulted depth (per occulted point)
Apparent velocity is 16.9 km/sec on the sky relative to the star, or, 18.5 arcsec/hr.
Position angle of asteroid motion is 77.5 degrees
The recommended exposure time corresponds to 8.4 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 28.2 km.
The sky-plane scale is 3278.1 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, maximum of 2.5 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
