Occultation event with (5648) Axius, event index number 4577
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/06 05:51:11 UTC
J2000 position of star is 06:02:23.8 +28:56:34
Equinox of date position of star is 06:04:06.2 +28:56:26
Star is 98 degrees from the moon. Moon is 9% illuminated.
Stellar brightness G=10.9, apparent brightess of occulting body is G=15.0
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 39.6 per integration for unocculted signal
Expected flux drop is 98% with SNR of 38.8 for the occulted depth (per occulted point)
Apparent velocity is 11.5 km/sec on the sky relative to the star, or, 12.7 arcsec/hr.
Position angle of asteroid motion is 126.4 degrees
The recommended exposure time corresponds to 1.4 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 33.4 km.
The sky-plane scale is 3237.5 km/arcsec.
Diameter estimates:
65.8 km assuming a 5% albedo, maximum of 5.7 sec for a central chord
26.9 km assuming a 30% albedo, maximum of 2.3 sec for a central chord
Cross-track diameter of 59.3 km used for deployment plan.
