  1. Stargazing 101UDI-172-M1 We went to John Rowe’s Farm by Caesar’s Creek October 20, 2009

  2. Orionid Meteor Shower • Annual meteor showers occur when left over debris from comets intersect our orbit around the Sun. • Best time to see the most meteors is between 1:00 am and dawn • When the Earth is rotated “face first” into the shower • The meteors are like bugs hitting the windshield of a car • Bugs don’t splatter on the side and rear windows NightWatch, p. 160

  3. Orionid Meteor Shower • Orionid Meteor Shower peaks tonight • Named so because the meteors appear to radiate from the Orion constellation • We are passing through the debris trail of Halley’s Comet • 30-50 meteors per hour • AccuWeather article • http://www.accuweather.com/mt-news-blogs.asp?partner=accuweather&blog=astronomy&pgurl=/mtweb/content/astronomy/archives/2009/10/on_the_hunt_for_meteors.asp • Yahoo article • http://news.yahoo.com/s/space/20091020/sc_space/getoutorionidmeteorshowerpeaksovernight Orion rises in the SE around 2:30 am www.AccuWeather.com

  4. Iridium Flares • The Iridium communication satellites have a peculiar shape with three polished door-sized antennas, 120 degrees apart and at 40 degree angles with the main bus. Occasionally an antenna will reflect sunlight directly down to the Earth, creating a predictable and quickly moving illuminated spot of about 10 km diameter. To an observer this looks like an extremely bright flare in the sky with a duration of a few seconds. www.en.wikipedia.org

  5. Iridium Flares • Tonight, there will be an Iridium flare at 8:30:15 pm (20:30:15 pm). • We will look for it in the East to NNE heavens-above.com
