This is a unique and exciting opportunity for RECON teams from Klamath Falls Oregon down to Yuma California. (9142) Rhesus is a Trojan Asteroid located in the L5 Lagrange point that trails 60 degrees behind Jupiter. The shadow track for this occultation passes over two dozen RECON sites in California and Arizona. Due to its proximity to Earth at less than 5AU, the uncertainties on this prediction are very low, making this a very strong occultation campaign opportunity. For all event details (including sense-up) visit: RECON Event Detail Page for (9142) Rhesus
The interactive GoogleMap below shows the predicted path of the occultation shadow (black lines) along with the 3-sigma uncertainty (blue lines). While this event is optional because we this announcement is going out just a week before the event, we encourage all teams within 3-sigma of the prediction from Yuma up to Klamath Falls to participate if possible.
