Occultation event with (5648) Axius, event index number 4681
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/14 05:26:22 UTC
J2000 position of star is 05:59:27.0 +29:20:31
Equinox of date position of star is 06:01:09.8 +29:20:31
Star is 163 degrees from the moon. Moon is 21% illuminated.
Stellar brightness G=13.2, apparent brightess of occulting body is G=14.9
Use an exposure time of 0.13 seconds with the standard RECON-QHY system.
SNR of 9.8 per integration for unocculted signal
Expected flux drop is 83% with SNR of 8.1 for the occulted depth (per occulted point)
Apparent velocity is 13.9 km/sec on the sky relative to the star, or, 15.7 arcsec/hr.
Position angle of asteroid motion is 118.1 degrees
The recommended exposure time corresponds to 1.8 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 34.8 km.
The sky-plane scale is 3183.2 km/arcsec.
Diameter estimates:
65.8 km assuming a 5% albedo, maximum of 4.7 sec for a central chord
26.9 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 59.3 km used for deployment plan.
