Occultation event with (4754) Panthoos, event index number 4545
Regions able to see the event: SAmericaS
Geocentric closest approach at 2026/11/02 05:31:31 UTC
J2000 position of star is 05:58:47.8 +09:51:17
Equinox of date position of star is 06:00:16.6 +09:51:18
Star is 47 degrees from the moon. Moon is 46% illuminated.
Stellar brightness G=16.9, apparent brightess of occulting body is G=15.4
Use an exposure time of 1.85 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 21% with SNR of 0.6 for the occulted depth (per occulted point)
Apparent velocity is 7.9 km/sec on the sky relative to the star, or, 8.5 arcsec/hr.
Position angle of asteroid motion is 58.5 degrees
The recommended exposure time corresponds to 14.7 km per image.
The 1-sigma error in the time of the event is 2.9 seconds.
The 1-sigma cross-track error in the shadow position is 31.1 km.
The sky-plane scale is 3346.1 km/arcsec.
Diameter estimates:
57.8 km assuming a 5% albedo, maximum of 7.3 sec for a central chord
23.6 km assuming a 30% albedo, maximum of 3.0 sec for a central chord
Cross-track diameter of 53.0 km used for deployment plan.
