At about 0446 UT on July 16 the asteroid Henrietta passed in front of a tenth-magnitude star inside a path across North America. Here's a video of that event. Check the stars in the middle right of the image, and look carefully! The soundtrack is the shortwave international time signal CHU. The equipment used was a Celestron NexStar 8 GPS with Fastar and an Astrovid StellaCam EX.
