The Best Times for Stargazing in Portsmouth
Observation in Portsmouth is most rewarding during the Spring months. During this time, the colder air masses over the Appalachia region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for Portsmouth Observers
Thermal equilibrium is key. Since Portsmouth temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Chesapeake Planetarium. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 1 at Bodie Island (82.3 miles away) remains the benchmark for regional sky quality.

Bodie Island
Cape Hatteras NS
Local Relevance
The scientific findings at Bodie Island provide Portsmouth residents with the most reliable data on regional atmospheric stability.
"Re-visit of site from 2007. Bodie lighthouse is not operational at this time. Recent Hurricane Irene has limited access to most of Cape Hattera NS. Previous sites at "Boardwalk 27" and Frisco are not accessible due to Hwy 12 washouts. We planned on capturing data at Oregon Inlet Campground for "dark site", but upon return at night, found intense (DOT construction style) lights at roadblock just south of campground. These lights were too bright to collect data. The lights are present as alight dome from the maintenance/housing site, appearing almost due south. There is also a single bright white, unshielded light in the maintenance area to the north. Other light domes are visible to the west and north (Nags Head, Kill Devil Hills, Kitty Hawk, etc.). The Milky Way is prominent in anorth south alignment and Jupiter is bright in the eastern sky. A few passing clouds were visible prior to and during the 1st data set. Overall, a nice clear sky for the second consecutive night. There is a high extinction due to the excessive moisture in the air. This site is somewhat shielded from sea spray by a row of sand dunes (5-10 meters high). While power had been off earlier in the week, I believe that most lights (especially to the north) or now operational. The lights of Hatteras Island may not be on because of no access, but the light dome from the temporary road block prevents us from seing anything to the south."
