On Sunday evening, November 12 local time, the shadow of this object will pass over northern Oregon and Southern Washington, providing an excellent opportunity to get a solid object profile for this peculiarly shaped main belt asteroid.  We STRONGLY encourage all of our teams from Goldendale Washington down to Northlake Oregon to participate in this optional campaign.  Most of these sites are guaranteed a positive event as long as skies are clear.

All other RECON teams are welcome to observe as well, both as good practice with your equipment and to potential capture one of Kleopatra’s two known moons.

Below are details on this optional occultation opportunity.  Note that the information below is not the standard TNO information because this is a main belt event predicted using IOTA tools.

Recording Window: 03:56-03:57 UT
Sense-up: 4x-8x (will vary with sky conditions; make sure you can see target star and at least one comparison star on screen)
