Expert Tips for Swarthmore Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Swarthmore, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the PA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Meadow south of Church House (30.6 miles away) remains the benchmark for regional sky quality.

Local Relevance
The scientific findings at Jockey Hollow provide Swarthmore residents with the most reliable data on regional atmospheric stability.
"Site next to Wick House in a field north of the orchard. Seeing very good, transparency fair. Very humid, dew on the grass. No part of the sky is dark, a gradient of sky brightness from horizon to zenith. The sky is grayish white, near the NYC and Newark light dome some peach color seen. Very bright near the horizon, which is actually at least 10 degrees above the true horizon. The site is in a "hollow" and has tall trees all around, so the brightest parts of light domes are masked. No distinct "domes" are seen, the sky is bright all around except toward the west, which looks dark by comparison."
