Moon Phase: 11.59% illuminated (waxing crescent)
      Rise: 8:50am
       Age: 3d 11h 16m since last New Moon

We hope to see you here for a night under the stars - now in our seventeenth year!
Tonight we'll have a thin waxing crescent Moon setting at 11:00pm. After that, the DSO's (Deep Space Objects) we love to see will be ours for the asking. Saturn, with its beautiful rings and six of its moons will be visible until it sets at 2:30am. Mars is visible, but very small and getting smaller every day now setting at 1:15am. Jupiter is nowhere to be seen since it's a morning object now rising nearly two hours 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. Many 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 98 minutes after sunset and may be able to be seen tonight
    Venus rises 76 minutes before sunrise and is a beautiful thin waxing crescent
    Earth is what you'll be standing on as you look up. ;^)
    Mars is easily visible after sunset and sets at 1:15am tomorrow morning
    Jupiter is a morning object now rising nearly two hours before sunrise
    Saturn is magnificent to see in our telescopes and sets at 2:30am tomorrow morning
    Uranus rises at 1:35am tomorrow morning and is visible this evening if you stay extremely late
    Neptune rises 12 minutes after midnight and is visible this evening if you stay extremely late
 
  Pluto rises at 9:00pm, but so incredibly small and dim that we can't see a thing in our telescopes!
    Moon is a 12% illuminated waxing crescent setting at 11:00pm 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".
