Occultation event with (5476) Mulius, event index number 4663
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/13 07:03:54 UTC
J2000 position of star is 05:58:29.5 +08:55:03
Equinox of date position of star is 05:59:57.7 +08:55:05
Star is 161 degrees from the moon. Moon is 14% illuminated.
Stellar brightness G=14.0, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.25 seconds with the standard RECON-QHY system.
SNR of 8.8 per integration for unocculted signal
Expected flux drop is 87% with SNR of 7.7 for the occulted depth (per occulted point)
Apparent velocity is 12.7 km/sec on the sky relative to the star, or, 13.6 arcsec/hr.
Position angle of asteroid motion is 63.9 degrees
The recommended exposure time corresponds to 3.2 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 25.9 km.
The sky-plane scale is 3372.4 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
