Occultation event with (4754) Panthoos, event index number 4353
Regions able to see the event: SAmericaS
Geocentric closest approach at 2026/10/06 08:30:09 UTC
J2000 position of star is 05:59:26.4 +10:44:24
Equinox of date position of star is 06:00:55.5 +10:44:24
Star is 51 degrees from the moon. Moon is 20% illuminated.
Stellar brightness G=13.5, apparent brightess of occulting body is G=15.7
Use an exposure time of 0.16 seconds with the standard RECON-QHY system.
SNR of 9.6 per integration for unocculted signal
Expected flux drop is 88% with SNR of 8.5 for the occulted depth (per occulted point)
Apparent velocity is 7.6 km/sec on the sky relative to the star, or, 7.5 arcsec/hr.
Position angle of asteroid motion is 132.9 degrees
The recommended exposure time corresponds to 1.2 km per image.
The 1-sigma error in the time of the event is 3.1 seconds.
The 1-sigma cross-track error in the shadow position is 30.8 km.
The sky-plane scale is 3610.0 km/arcsec.
Diameter estimates:
57.8 km assuming a 5% albedo, maximum of 7.6 sec for a central chord
23.6 km assuming a 30% albedo, maximum of 3.1 sec for a central chord
Cross-track diameter of 53.0 km used for deployment plan.
