Sample Itinerary

What to Wear

Not sure how to dress for the weather? Follow these tips to dress for success during your visit!

The average high temperature in Flagstaff during the month of July is 81.3 F, but the average low temperature is a cool 50.7 F. Temperatures can dip down into the 40s and even into the upper 30s on rare occasions during the summer. If you plan to visit Lowell from morning to evening, be sure to bring a jacket in case the temperature drops when the Sun goes down!

If you want to get the most out of your visit by going on tours of our historic campus and enjoying evening stargazing, you should be prepared to do some walking! The walking paths on our campus can get fairly steep in some areas, and tours require a lot of walking and standing. If you need a break, there are benches placed throughout our campus. They’re also a great place to sit and take in the scenery!

Did you know that you can get sunburned more easily at high elevations? It’s true — research indicates that for every 1,000 ft of elevation gain, the Sun’s UV rays intensify by 8-10% because of the thinning atmosphere. Flagstaff sits at an elevation of 7,000 ft, so it’s especially important to make sure you use sunscreen during your visit to the observatory.

Summer Constellations


The Swan

Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. Cygnus is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross.


The Eagle

Aquila is a constellation on the celestial equator. Its name is Latin for ‘eagle’ and it represents the bird that carried Zeus/Jupiter’s thunderbolts in Greek-Roman mythology. Its brightest star, Altair, is one vertex of the Summer Triangle asterism.


The Hero

Hercules is a constellation named after Hercules, the Roman mythological hero adapted from the Greek hero Heracles. Hercules was one of the 48 constellations listed by the second-century astronomer Ptolemy, and it remains one of the 88 modern constellations today.


The Centaur

Sagittarius is one of the constellations of the zodiac and is located in the Southern celestial hemisphere. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy and remains one of the 88 modern constellations. Its old astronomical symbol is. Its name is Latin for “archer”.


The Scorpion


The Serpent-Bearer

Ophiuchus (pronounced OFF-ee-YOO-kuss) is a large constellation straddling the celestial equator. Its name comes from the Ancient Greek word for “serpent-bearer”, and it is commonly represented as a man grasping a snake. The serpent is represented by the constellation Serpens.

The key to finding Ophiuchus is being able to identify Scorpius. Scorpius is a fairly easy constellation to point out because of its distinctive hook-like shape. The ‘head’ of Ophiuchus is also located near the head of Hercules, so use that constellation to help guide your way.

Meteor Crater & Barringer Space Museum

Over 50,000 years ago space and earth came together when a huge iron-nickel meteorite, approximately 150 feet wide and weighing several hundred thousand tons, impacted an area outside of Flagstaff, Arizona, with a force 150 times greater than an atomic bomb. The result of this impact was devastation for miles and the creation of the giant bowl-shaped cavity we call Meteor Crater, which measures 550 feet deep and almost a mile wide.

Nestled on its north rim, Meteor Crater Visitor Center is one of the most popular attractions in Northern Arizona. See the crater for yourself and explore interactive exhibits in the Barringer Space Museum!
