Occultation event with (7352) Hypsenor, event index number 1108
Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/07/03 09:33:40 UTC
J2000 position of star is 02:15:37.8 +05:45:05
Equinox of date position of star is 02:16:58.2 +05:52:09
Star is 162 degrees from the moon. Moon is 56% illuminated.
Stellar brightness G=15.0, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 7.8 per integration for unocculted signal
Expected flux drop is 68% with SNR of 5.3 for the occulted depth (per occulted point)
Apparent velocity is 24.0 km/sec on the sky relative to the star, or, 21.6 arcsec/hr.
The recommended exposure time corresponds to 14.4 km per image.
The 1-sigma error in the time of the event is 1.4 seconds.
The 1-sigma cross-track error in the shadow position is 13.5 km.
The sky-plane scale is 4005.1 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, aximum of 2.5 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 60.5 km used for deployment plan.
