On August 23, RECON sites from Northern California to Bishop successfully recorded an occultation by (489) Comacina. Participants in Tulelake, Fall River Mills, Susanville, Greenville, Quincy, Portola, and Bishop all measured the occultation event. The chord diagram below compiles RECON data and observations from other IOTA members to provide an estimate of the asteroid size and shape.

Unfortunately, heavy smoke from the Rim Fire burning in Yosemite Park obscured the skies for observers in Reno, Carson City, Gardnerville, Yerington, and Hawthorne. The image below shows a daytime shot from Carson City during this smoky time!
