Due to the COVID-19 pandemic, people across the globe have been confined to their homes with limited outdoor activities. We amateur astronomers, however, are lucky to have the night sky to explore, untouched by human concerns. Lockdown or not, this year’s October Ghost Hunt — a fun activity that, like the Messier marathon, challenges amateur astronomers to view 109 targets in a single night — may just be the medicine we need to lift our spirits. I originally wrote about the Ghost Hunt, whose targets are carefully selected from several deep-sky observing lists, in the October 2009 issue.

Because New Moon occurs October 16 this year, I’ve made adjustments to the original list, as five objects will be too low to see well: M3, M53, NGC 3242, NGC 4699, and NGC 4725. For the 2020 Ghost Hunt, these have been replaced with M10, M12, NGC 1931, NGC 4656, and NGC 6426. The 2020 Ghost Hunt list, presented in order of right ascension, can be viewed online at www.Astronomy.com/Ghost2020.

Texas stargazing

Last October 26, Lloyd Lashbrook and some 25 members of the Texas Astronomical Society of Dallas drove to their dark site in southern Oklahoma with 15 telescopes to conduct what he “hoped to be the first of many Ghost Hunts.” Lashbrook said the evening, which included a fall picnic, was a great success. The competition was four categories: manual telescope, electronically aided scope, binoculars, and astrophotography.

The winners in each category (who saw or imaged the most objects) received a special gold or silver Ghost Hunt medal. John Wagoner won the gold medal in the manual telescope and binocular categories, Larry Ammann took the gold medal in astrophotography, and Les Matyas was the winner in the “aided telescope” category, as he used an electronically aided telescope to capture 30-second exposures of 82 Ghost Hunt objects — more than anyone else. “I never dreamed that someone would do that,” Lashbrook says.

“While no one got through the entire list,” Lashbrook says, “we had a great time. Several new members learned about the sky and observing it. Now they have become regular members of our club.”

Busting the ghosts

One benefit of the society’s first Ghost Hunt is that they came up with a plan of attack to help participants search efficiently and rapidly. Last year, Lashbrook also suggested substitutes for four objects that beginners may find too difficult to detect. I noted these in parentheses with an asterisk in the “Facing south” group below. Here is the group’s breakdown for attacking the 2020 Ghost Hunt. Observers should start with the first object listed, then move to the next. All times are local.

Future plans

“Now that we have had the first Ghost Hunt,” Lashbrook says, “enthusiasm runs high in the club” for this month’s — whether it’s solitary, virtual, or social.

The society also plans to hold a Ghost Hunt at the Palo Pinto Star Party on Saturday, October 3. It will be a forerunner to the main event and will include the Fort Worth Astronomical Society. “We will just keep pushing until this thing starts rolling on its own,” Lashbrook says.

And remember, you’ll find a list of targets updated for 2020 online at www.Astronomy.com/Ghost2020. As always, send your thoughts and observations to sjomeara31@gmail.com. I’d really like to know how many Ghost Hunt targets you saw.
