Occultation event with (3063) Makhaon, event index number 3657
Regions able to see the event: Australia,NZ
Geocentric closest approach at 2026/04/19 08:40:35 UTC
J2000 position of star is 12:01:05.7 -16:18:28
Equinox of date position of star is 12:02:26.6 -16:27:15
Star is 131 degrees from the moon. Moon is 5% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=13.4
Use an exposure time of 1.90 seconds with the standard RECON-QHY system.
SNR of 3.5 per integration for unocculted signal
Expected flux drop is 7% with SNR of 0.2 for the occulted depth (per occulted point)
Apparent velocity is 14.4 km/sec on the sky relative to the star, or, 17.3 arcsec/hr.
Position angle of asteroid motion is 123.0 degrees
The recommended exposure time corresponds to 27.3 km per image.
The 1-sigma error in the time of the event is 2.9 seconds.
The 1-sigma cross-track error in the shadow position is 23.9 km.
The sky-plane scale is 2995.0 km/arcsec.
Diameter estimates:
118.0 km assuming a 5% albedo, maximum of 8.2 sec for a central chord
48.2 km assuming a 30% albedo, maximum of 3.4 sec for a central chord
Cross-track diameter of 111.7 km used for deployment plan.
