ASTROBLAST 2020 HAS BEEN CANCELLED Click here to learn about AstroBlast 2019. The Oil Region Astronomical Society was founded in 1993. The first observatory was located in Two Mile Run County Park, Venango County, PA. In 2014, the ORAS Observatory moved to a new site. Land was donated for an observatory in southeastern Venango County, off Camp Coffman Road -- a location with a darker sky and a better view to the south. The process of building a new observatory and installing bigger and better telescopes is now at an end! |

Clear Sky Chart
Click below for current and projected ORAS Observatory sky conditions from the Clear Sky Chart.
At a glance, the Clear Sky Chart shows when it will be cloudy or clear for up to the next two days. It's a prediction of when the ORAS observatory site will have good weather for astronomical observing. Click on "HELP" in the lower right hand corner of the Clear Sky Chart for information on how to read the chart.
The Clear Sky Chart was developed by the Canadian Meteorological Centre. It is now sponsored by the Northern Virginia Astronomical Club, the Edmonton Centre and the Royal Astronomical Society of Canada. The managers of the chart run three computer weather simulations every twelve hours. The output looks just like satellite pictures, but the dates are from the future.
