EVAC Member Star Parties


EVAC currently does not officially support any local star parties. Some members do gather at  Picket Post Trailhead during the weekend before and on the weekend of the New Moon.  Due to Forest Service rules, a Ranger may be present from spring to fall.  Gates are locked at sunset when the Ranger is present.  For this reason, members are encouraged to use open areas off the road before Picket Post if the gates are locked.  See Observing Sites below.

All Arizona Star Party

Our annual dark sky weekend will be November 1-2, 2024 and will be held at the North Hovatter observing field (see directions above).  This is a great chance to gather in the desert to observe with your fellow astronomy enthusiasts.  Please drive SLOWLY to avoid dust.  Park near the north entrance if you will be leaving early.  Avoid white lights and have fun.

  • 5:00pm  Gather at the hospitality tent for a potluck.

Observing Sites

Picket Post Trailhead Site

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.

How To Get To Picketpost Mountain Trailhead


Site coordinates: 

  • N 33º 16' 21" 

  • W 111º 10' 35"    

  • 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.

Antennas Site

This is another site that is near the Hovatter North site. It is on BLM land and the Saguaro Astronomy Club has a use permit for it. Site Map and Directions are below. Please park on the edge of the site if you are leaving early. Please avoid white light and make as little dust as possible.

How To Get To The Antennas Site

Antenna Map.png

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

From Phoenix:

  1. Go west on I-10 to Hovatter Rd at exit 53 or about 40 miles west of Palo Verde Nuclear Power Generating Station.

  2. Turn left over the freeway, drive over the canal.

  3. When you cross the canal, turn right.

  4. Go .1 miles to and turn left onto dirt road.

  5. Travel past the antennas and turn right at next opportunity.

  6. Go through two washes and the site is on the left.
