Two asteroid star occultations 17 minutes apart

About this image

This was a rare happening, capturing two succesful asteroid occultations within 17 minutes of each other.  Each is entirely different. The first was a very quick event only just detected, the second lasted nearly 12 seconds but becuse the asteroid was brighter than the star the drop in magnitude for the event was just 0.2 but still luckily detected.
