Occultation event with (5648) Axius, event index number 4864
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/24 23:58:49 UTC
J2000 position of star is 05:54:10.0 +29:51:23
Equinox of date position of star is 05:55:53.4 +29:51:35
Star is 21 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=15.4, apparent brightess of occulting body is G=14.8
Use an exposure time of 0.85 seconds with the standard RECON-QHY system.
SNR of 6.1 per integration for unocculted signal
Expected flux drop is 36% with SNR of 2.2 for the occulted depth (per occulted point)
Apparent velocity is 16.7 km/sec on the sky relative to the star, or, 19.2 arcsec/hr.
Position angle of asteroid motion is 111.0 degrees
The recommended exposure time corresponds to 14.2 km per image.
The 1-sigma error in the time of the event is 0.1 seconds.
The 1-sigma cross-track error in the shadow position is 35.2 km.
The sky-plane scale is 3127.7 km/arcsec.
Diameter estimates:
65.8 km assuming a 5% albedo, maximum of 3.9 sec for a central chord
26.9 km assuming a 30% albedo, maximum of 1.6 sec for a central chord
Cross-track diameter of 59.3 km used for deployment plan.
