Arizona City is the site of the annual All-Arizona Star Party. The observing
field is located midway between Phoenix and Tucson, west of Interstate 10. The sky conditions are reasonably good, almost matching those of the Vekol Road site. The site offers the right combination of dark skies, good visibility and temperate nights that will encourage you to stay up well past your bedtime! There are the predictable glows from Phoenix and Tucson, but not much else to complain about. The nearby cotton fields make this another very dusty place, especially when stirred up by 50 to 100 arriving astronomers. Most of the flora is small creosote bushes, so horizons are very low. It is important to note that this site is on private land. This is a primitive site - so if you need something you'll have to bring it with you! Porta-Potties will be available on site. Attendees are welcome to camp overnight at AASP.
To get to the site of the All-AZ Star Party: Take I-10 to Exit 200, Sunland Gin Road. Take this road south (a right turn if coming from Phoenix, a left turn if coming from Tucson). Note: this is the closest place for gas and food after leaving the interstate. The paved road continues for 17 miles, then it turns sharply to the west (right). Continue west for 4 miles. The main road turns south (left) just past the "Silverbell Estates" sign. Continue south for 3 miles past the sign, the road veers off to the west (right). Continue on the road for another 5 miles, where it passes through a gate. Take an immediate left after the gate, and continue for 0.7 miles. Take the next right on a road that leads into an open field. Just follow the signs along the road into the observing field. If you must leave early, please park toward the north end of the field. Likewise, if you are spending the night, park to the south. Click
