Occultation event with (5476) Mulius, event index number 3102
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/01/03 04:50:55 UTC
J2000 position of star is 03:21:01.1 +07:56:03
Equinox of date position of star is 03:22:24.9 +08:01:35
Star is 52 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=11.8, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 24.0 per integration for unocculted signal
Expected flux drop is 98% with SNR of 23.6 for the occulted depth (per occulted point)
Apparent velocity is 6.3 km/sec on the sky relative to the star, or, 6.7 arcsec/hr.
Position angle of asteroid motion is 90.1 degrees
The recommended exposure time corresponds to 0.8 km per image.
The 1-sigma error in the time of the event is 0.2 seconds.
The 1-sigma cross-track error in the shadow position is 27.1 km.
The sky-plane scale is 3381.5 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, maximum of 6.8 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 2.8 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
