       Age: 19d 2h 24m since last New Moon
We hope to see you here for a night under the stars - now in our seventeenth year!
Tonight we'll be viewing without the Moon since it won't be rising until after midnight and won't clear the trees to the east of the observing field until 2:00am Saturday morning. The DSO's (Deep Space Objects) we love to see will be ours for the asking. Saturn, with its beautiful rings and five of its moons will be visible until it sets at 3:26am. Mars is visible, but very small and getting smaller every day. Jupiter is nowhere to be seen since it's a morning object now rising an hour before sunrise. Uranus and Neptune rise extremely late and won't be available to us. Colorful double stars and open clusters made up of hundreds of stars that will look beautiful; the globular clusters will be fantastic as will the planetary nebula formed by dying stars. The diffuse nebula and emission nebula where stars are being born will be visible. Galaxies will be available to us.

How about the planets...which ones can we see tonight? 

    Sun is obviously unavailable to us, it IS night time after all ;^)
    Mercury is an evening object now setting 73 minutes after sunset and lost in the glare of the Sun
    Venus is now rising 11 minutes before sunrise but is lost in the Sun's glare
    Earth is what you'll be standing on as you look up. ;^)
    Mars is easily visible after sunset and sets at 1:57am tomorrow morning
    Jupiter is a morning object now rising an hour before sunrise and lost in the glare of the Sun
    Saturn is magnificent to see in our telescopes and sets at 3:26am tomorrow morning
    Uranus rises at 2:29am tomorrow morning and won't be visible this evening
    Neptune rises at 1:08am tomorrow morning and won't be visible this evening
 
  Pluto rises at 9:56pm, but so incredibly small and dim that we can't see a thing in our telescopes!
    Moon is a 73% illuminated waning gibbous rising 14 minutes after midnight tonight

     Question: Will Mars be "as big as a Full Moon on August 27!" ???
       Answer: ABSOLUTELY NOT!!!

     Question: Will there be "Two Full Moons in the Sky!" ???
       Answer: ABSOLUTELY NOT!!!

     Mars was the closest in recorded history on August 27, but that was only in 2003, not every year!
     At that time, it appeared to be 1/75th the apparent diameter of the Moon!  NOT the "same size as the Full Moon".
