Public Observing Event
at the ACA Observatory


Quasar 3C 273

Our featured object tonight is Quasar 3C 273. This quasar shines at about 13th magnitude. That's pretty dim, so we'll need to wait until after nautical twilight (10:06pm) to get enough darkness to see the object. We'll have a 15th magnitude star map for you to study before proceeding to the eyepiece so you can positively identify the object. With good observing conditions, some patience, and a little luck, you'll be able to see 1/6th the distance across the observable Universe, 2.4 billion light-years distant; that's 14,000,000,000,000,000,000,000 (14 sextillion) miles.

Of course Jupiter, Saturn, globular clusters M3 & M13, Whirlpool Galaxy, Ring Nebula, Sombrero Galaxy, and a few double stars are also on the observing list. We'll have the Best Free Coffee in Akron brewing all observing session and a preview of acoustical treasure planned for our June 21st star party.

The observatory will be open at 8:45pm with Jupiter in the eyepiece. A three day old Moon will be in the evening sky; but setting early. We hope to see you here!

Solar System objects rise/transit/set times from the ACA Observatory on the date of this event...

New feature: The "T" on each object's line in the chart above indicates the time of transit in addition to the rise and set times for the object.

Jet Stream (updates automatically to latest available image)
    The Jet Stream affects astronomical "seeing" (steadiness of the air)
    If we're in a gray area, seeing will not be as good as in a white area.
    If we're in a white area, the shorter the arrows, the better.
