SPOOKY SENSATION

3 October 2020 Viewing Schedule

SUBJECT TO CHANGE. ANY UPDATES OR ALTERATIONS WILL BE POSTED AT THE BOTTOM OF THIS PAGE AS A PDF.

7:00 pm to 10:00 pm = OBJECT: Jupiter♃
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)

7:30 pm to 10:00 pm = OBJECT: Saturn♄
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)

7:57 pm to 8:00 pm = EVENT: Visible Pass of an H-IIA Rocket Body
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)

8:00 pm to 8:15 pm = ACTIVITY: The Magnitude Scale
HRPO personnel will explain what the magnitude scale is, and then will utilize 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)

8:00 pm to 10:00 pm = EVENT: Ganymede Transits in Front of Jupiter♃
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)

8:15 pm to 8:30 pm = STORY: Great Square of Pegasus
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)

8:15 pm to 9:00 pm = OBJECT: The Andromeda Galaxy (Messier 31)
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)

8:21 pm to 8:25 pm = EVENT: Visible Pass of the Lacrosse 4 Rocket
This Titan 4B sent up an American military satellite in August 2000. (distance 571 kilometers / magnitude 1.3)

8:30 pm to 9:00 pm = OBJECT: The Owl Cluster (Caldwell 13)
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)

8:40pm to 8:46pm = EVENT: Visible Pass of the Cosmos 2082 Rocket
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)

8:45 pm to 9:00 pm = STORY: Job’s Coffin
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)

8:45 pm to 9:15 pm = OBJECT: The Moth Cluster (Melotte 232)
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)

8:45pm to 10:00pm = OBJECT: Mars♂
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)

9:00 pm to 9:30 pm = OBJECT: Neptune♆
Although huge, Neptune♆ is also very far away. It’s deep rich blue tone, however, is striking. (distance 29 astronomical units / magnitude 7.8)

9:15 pm to 10:00 pm = OBJECT: Waning Gibbous Moon
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)

9:45 pm to 10:00 pm = OBJECT: The Demon Star
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 at 7:00 pm, but there are a limited number. We strongly encourage visitors to bring binoculars.
