The October meeting of the Pittsburgh Chapter of the International Dark-Sky Association was held at 6:30 pm on Monday, October 22, 2018, Connan Room in the Cohon University Center at Carnegie Mellon University.

The City of Pittsburgh plans to begin changing streetlights to LEDs in 2019. In the works? A new Metro21 grant at CMU to make a light pollution map of Pittsburgh, before, during and after the installation using UAVs.

We’ll also continue discussion of our various projects:

  • education and public outreach

  • local astrophotography

  • new IDAPgh website

  • comparisons of the sky in Pittsburgh from long ago until now

  • creation of attractive content for our social media (Facebook)

  • membership coordination

  • City Council meeting attendance (Schedule)

  • radio interviews of members

  • children’s light pollution book

  • analysis of eight years of Allegheny Observatory All-Sky camera data (to put a number to the increase of light pollution in the city)

  • taking nighttime data of Pittsburgh uplights with a weather balloon (possibly with Pitt Shadow Bandits)

  • ISS astronaut photos of Pittsburgh at night

  • using phone apps to measure skyglow all over the city (Dark Sky Meter for iPhone users, Loss of Night for Android users)

  • asking an astronaut to visit Pittsburgh and speak about what the night side of Earth looks like from above (Request Guidelines)

Triangulation: Dark Skies

Announcing a new call for stories for a themed anthology of science fiction, fantasy and horror stories celebrating dark skies. Triangulation is Parsec Ink’s themed speculative fiction anthology, now in its 15th year. Everyone is eligible to send in a story. We’re looking for work from new as well as established authors.

The purpose of the anthology was to give Pittsburgh writers a chance to see what it’s like to sit on the other side of the desk. Editors change every year or two. Each editor picks the theme for their anthology.

Triangulation: Dark Skies will be a celebration of the dark. Light pollution is a danger to human health, to animals and plants in the nighttime ecosystem and to the future of astronomical research on our planet. It wastes billions of dollars a year. Glare from unshielded lights causes safety hazards for drivers and pedestrians. We don’t yet know the full effect of making the night in cities 100 times brighter, but it deserves our focused attention. Want to know more? Start at the comprehensive website of the International Dark-sky Association.

Storifying an issue is a proven way to engage an audience. The hope is that readers will identify with proactive characters making decisions, experiencing firsthand the dangerous trend to light up the night and suffering the consequences. This issue will be given to attendees at a Dark Sky Conference in 2019 at Carnegie Mellon University, then widely available for purchase.

This anthology not the place for stories about the creeping horrors in the dark, which we are losing at the speed of light, but rather a exploration of the theme — celebrating our place in the universe and the ability to see into the depths of space.

Each story must contain speculative elements. While we’d love to hear about what the sky was like when you were a kid, accepted stories will weave a sense of wonder into an engaging human (or monster, alien, whatever) tale. Imaginative incorporation of the theme is a necessity. Past, present, future accounts. Cautionary tales. Secondary worlds and altered timelines. The effects of light pollution are many and varied – feel free to explore any aspects, from neurobiological studies to life in an alien star system to legends out of time.

Word count: under 5000 words (with a preference for stories around 3000 words). No minimum word count.

Payment: 4 cents a word on acceptance. Authors will receive an ebook and be mailed one printed copy of the anthology, with the option to buy further issues at one half the cover price (plus shipping). We purchase First North American serial rights and electronic rights for the downloadable version. All subsidiary rights are released upon publication, which is expected to be May 2019.

The submission window is November 17 to January 31, 2019. No reprints, fanfic, multiple or simultaneous submissions.

We use Submittable for electronic submissions. Register for a free account. Put your story in standard manuscript format and upload it in .doc, .docx or .rtf format.
