Occultation event with (76867) 00YM5, event index number 4860
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/24 20:44:03 UTC
J2000 position of star is 04:06:09.3 +38:46:26
Equinox of date position of star is 04:07:57.5 +38:50:41
Star is 13 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.4, apparent brightess of occulting body is G=15.3
Use an exposure time of 1.00 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 27% with SNR of 0.8 for the occulted depth (per occulted point)
Apparent velocity is 19.2 km/sec on the sky relative to the star, or, 22.7 arcsec/hr.
Position angle of asteroid motion is 97.3 degrees
The recommended exposure time corresponds to 19.2 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 28.7 km.
The sky-plane scale is 3052.8 km/arcsec.
Diameter estimates:
48.3 km assuming a 5% albedo, maximum of 2.5 sec for a central chord
19.7 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 42.8 km used for deployment plan.
