Occultation event with (7352) Hypsenor, event index number 1056
Regions able to see the event: Australia
Geocentric closest approach at 2025/06/13 18:27:15 UTC
J2000 position of star is 02:03:12.4 +05:03:43
Equinox of date position of star is 02:04:32.3 +05:11:00
Star is 99 degrees from the moon. Moon is 94% illuminated.
Stellar brightness G=14.8, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.45 seconds with the standard RECON-QHY system.
SNR of 7.3 per integration for unocculted signal
Expected flux drop is 72% with SNR of 5.2 for the occulted depth (per occulted point)
Apparent velocity is 31.0 km/sec on the sky relative to the star, or, 26.6 arcsec/hr.
The recommended exposure time corresponds to 13.9 km per image.
The 1-sigma error in the time of the event is 1.2 seconds.
The 1-sigma cross-track error in the shadow position is 14.3 km.
The sky-plane scale is 4189.9 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, aximum of 2.0 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 0.8 sec for a central chord
Cross-track diameter of 60.5 km used for deployment plan.
