PMDO (Poor Meadow Dyke Observatory) is a private sky survey which photographs a strip of the sky from 4d40 to 7d25 north each night, as weather permits. With a limiting magnitude of about 14, and a resolution of 14.1" per pixel, it can detect fainter objects than the Stardial survey. Its home page is sky-survey.com, and it is run by Steve Chambers, who's always a pleasure to talk to. He's managed to set up a system that monitors up to 100,000+ stars on a clear night. Unlike Stardial, with Steve's data, I can query his archive and get detailed photometric measurements of objects. Wow.
Here are some of the things I'm doing with this data:
Project #1: A set of tools for accessing the data archive. There's a lot of stuff in there
if you know how to get it. Since I've always had a knack for data visualization, this is a good
test. ;-) Here are the first tools of many:
Project #2: Search for variable stars, both known and new ones.
Here's a teaser ... this star is not listed in GCVS (as far as I know),
but here it is clearly going through a cycle:
Okay, a search turned up NSV 3434 at this location, an old red star mag 13.5-15.., unknown period. Worth keeping an eye on!
And here's a known variable, WX CMi, doing it's thing:
Project #3: After accumulating enough images, it may be possible to build
a photographic atlas of this band of the sky.
Here are some sample charts! (added Feb 2004)
Charts available: [001-006] - [007-012] - [013-018] - [098-103] - [104-109] - [110-115]
Project #4: Looking for asteroids & comets. While most of the undiscovered asteroids are way too faint (mag 18 to 22) to show up in PMDO images, you never know.
