Occultation event with (7352) Hypsenor, event index number 4028
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/08/17 03:32:26 UTC
J2000 position of star is 04:26:57.2 +13:57:18
Equinox of date position of star is 04:28:27.2 +14:00:47
Star is 132 degrees from the moon. Moon is 22% illuminated.
Stellar brightness G=16.3, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 38% with SNR of 1.2 for the occulted depth (per occulted point)
Apparent velocity is 19.1 km/sec on the sky relative to the star, or, 17.5 arcsec/hr.
Position angle of asteroid motion is 89.9 degrees
The recommended exposure time corresponds to 15.3 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 24.2 km.
The sky-plane scale is 3940.7 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, maximum of 3.2 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 47.7 km used for deployment plan.
