Occultation event with (5476) Mulius, event index number 4772
Regions able to see the event: NZ
Geocentric closest approach at 2026/11/19 12:29:53 UTC
J2000 position of star is 05:56:14.7 +08:40:52
Equinox of date position of star is 05:57:42.9 +08:40:59
Star is 99 degrees from the moon. Moon is 70% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 5.2 per integration for unocculted signal
Expected flux drop is 62% with SNR of 3.2 for the occulted depth (per occulted point)
Apparent velocity is 14.3 km/sec on the sky relative to the star, or, 15.5 arcsec/hr.
Position angle of asteroid motion is 69.5 degrees
The recommended exposure time corresponds to 8.6 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 26.5 km.
The sky-plane scale is 3333.8 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
