Member Star Parties


For many amateur astronomers, participating in club star parties is the best part of belonging to a club. These friendly nocturnal gatherings give observers a chance to talk about all things astronomical, look through many types of scopes and show off a few of their favorite sights. EVAC offers at least two star parties each month (weather permitting, of course.)

EVAC Member Star Parties


EVAC star parties are held at Picket Post Trailhead, near Superior on the Saturday closest to 3rd quarter moon and the Saturday closest to the new moon.

EVAC is not supporting member star parties at this time.

The site offers reasonably dark skies within an hour of most east Valley locations. A hill blocks a good bit of the Phoenix sky glow to the west, and Superior's minor glow is visible in the northeast.


The star party is usually well-attended and is especially suited to those just getting started. If you are in the market for a scope, this is the place to see a variety of scopes and talk to their owners or simply get advice on getting started.

How To Get To Picketpost Mountain Trailhead

  • Elevation 2375'

picket post star party map

This site is easily accessed by any vehicle.

  1. Take US 60 east past Florence Junction.

  2. As you come down from Gonzales Pass, watch out for the green Mile Marker 221 sign.

  3. Just past that you will see a yellow 'Truck Crossing' sign... and just past the sign is FR 231.

  4. The road is now easier to spot than in the past, as there is now a familiar brown sign indicating the trailhead.

  5. You'll know it's the right road because there is a small windmill visible just after you make the right turn.

  6. Follow the well-graded road about half a mile to where it dead-ends into another road.

  7. Another brown sign indicates that you should make a left turn (staying on FR 231) to get to the trailhead.

  8. This section of the road is asphalt.

  9. Follow the narrow road about a half mile until it ends at the trailhead.

  10. When you reach the trailhead, bear to the right and circle around until you see the larger, flat area.

     All Arizona Star Party - Cancelled

The Hovatter Airfield is no longer available to us to use as our dark sky location for the All Arizona Star Party. Both EVAC and the Saguaro Astronomy Club had an annual use agreement with the Bureau of Land Management to use

the site for club activities. The BLM transferred that land to La Paz County for the construction of a large solar energy facility resulting in the cancellation of our BLM agreement. The area now can not be used by either of our clubs for any reason since no use agreement exists with La Paz County.

We do not know when actual construction will start. Both

EVAC and SAC are working to find a replacement dark sky

site. However, because of the current health environment,

and the time it would take to find a new site and negotiate

a new use agreement with the new site owners, this year’s

All Arizona Star Party scheduled in October has been cancelled.

How To Get To Hovatter Airstrip

astronomy club star party map

The Salome Airfield is located two miles south of Interstate 10, and about ten miles west of Centennial, AZ.

  1. From Phoenix, go West on I-10 to Hovatter Rd at exit 53 (about 40 miles west of Palo Verde Nuclear Power Generating Station).

  2. Once off I-10 and onto the Hovatter Road overpass, turn left and proceed over the freeway and over the canal.

  3. When you cross the canal, turn hard left onto the AT&T Frontage road.

  4. Go 1.1 miles to a bend in the road.

  5. As the road veers to the SE, look for a road running due south at the same point - Tomson St. and head South for 1.8 miles. Note: Google Maps shows Tomson St. Apple maps and the road sign show Vinegaroon Road.

  6. You will come to a small left-right zig-zag, then see a chain link fence enclosing an area about 20 ft by 20 ft off to the East of the road

  7. This is the abandoned airfield's entrance.
