There’s a chill in the air—that can only be explained by science at Spooky Sensation – Highland Road Park Observatory. Come join us for a marshmallow roast with eerie true-life STEM stories, a scavenger hunt game to earn wicked prizes, physical science demos that will make you scream, and more.
Attendees can enjoy views of the Sun and all five outer planets: Mars, Jupiter, Saturn, Uranus, and Neptune. Activities will include the Twilight Deepening, Magnitude Stepdown, Scope-on-a-Rope, and a brief discussion of the mysterious X-37B spaceplane. Other celestial targets include the Pleiades Star Cluster, the double star Albireo, the Job’s Coffin asterism, and the Andromeda Galaxy.

Spooky Sensation Event Viewing Schedule:

The largest planet has an extremely intense magnetic field and is currently being investigated by the Juno spacecraft. (4.9 astronomical units / magnitude -2.3)

The ringed beauty will be seen. Try to spy the Cassini Division, the largest gap in the planet’s ring system. (9.7 astronomical units / magnitude 0.5)

Part of a Japanese launch system, this piece of space junk should be visible under the correct conditions. Here’s to hoping we have them. (distance 534 kilometers / magnitude 1.7)

HRPO personnel will explain what the magnitude scale is, and then will ultilize the stars Vega, Fomalhaut, Polaris and Albireo to illustrate how dim stars get as one progresses down the ladder of the scale. (distances 25, 25, 431 and 385 light-years respectively / magnitudes 0.0, 1.1, 2.0 and 3.2 respectively)

The largest moon in the Solar System must have known about this night’s celebration. It will give a memorable show by orbiting in front of its parent planet. (Ganymede magnitude 4.9)

As Pegasus the Winged Horse rises in the east, you’ll hear a story recounted about this majestic mythological creature. (distance of four corners 97 to 335 light-years / magnitudes of four corners 2.0 to 2.8)

The closest spiral to our own Milky Way is rising high while twilight is ending. Sadly, the local light pollution only allows a view of the galaxy’s core. (distance 2 million light-years / magnitude 4.5)

This Titan 4B sent up an American military satellite in August 2000.
(distance 571 kilometers / magnitude 1.3)

A perfect eerie addition to the night’s proceedings. Can you spot the two bright “eyes” of the cluster? (distance 7900? light-years / magnitude 6.4)

The Cosmos series of satellites followed the USSR’s Sputniks. This rocket body has been orbiting for over three decades. (distance 844 kilometers / magnitude 2.0)

The constellation Delphinus the Dolphin harbors the traditional tales of Greek wonder about the mammals of the sea—though the origin of the asterism’s creepy name is lost to the ages. (distances of four corners 98 to 241 light-years / magnitudes of four corners 3.6 to 4.4)

If at this point you’ve had enough of creepy crawlies, try a flying creepy. This object will require a little patience to allow your eyes to adjust to the dim glow of the cluster. (distance ~2500 light-years / magnitude 6.3)

Mars is currently the closest it will be to the Earth for the next thirteen years. If the sky is steady and crisp, and your eyes sharp, you may see a polar cap and contrasting surface colors. (distance 62 million kilometers / magnitude -2.5)

Although huge, Neptune is also very far away. It’s deep rich blue tone, however, is striking.
(distance 29 astronomical units / magnitude 7.8)

A variety of features await the viewer: rays of ejecta, the Bay of Rainbows and the Marsh of Sleep to name a few. (distance 404,000 kilometers / magnitude -12.5)

The Spooky Sensation closes with the rising of evil. At least that’s what the Ancients thought. Algol was the first eclipsing binary discovered; a companion star periodically blocks some of its light. (magnitude ?? ; It can range from 2.1 to 3.4 ; What do you think it is?)
➞All viewing is weather permitting. Visible pass predictions are almost certain to have slight alterations come 3 October.
➞Remember: the lower the magnitude number, the brighter the object.
➞Binocular checkout from HRPO front desk will be available, but there are a limited number. We strongly encourage visitors to bring binoculars.
