Some cirrus rolled in at the end of the night, but not enough to keep the Tucson camera from detecting 28 meteors. Amazingly 4 of them were from the minor Sigma Hydrid (HYD) shower. According to Sirko Molau’s analysis of video meteor data, the Sigma Hydrids have a broad peak covering the nights of Dec 3-13. Perhaps the 6 Sigma Hydrids picked up over the past 2 nights are a hint of more activity to come.
