October 2003 Dark Sky Observing Time

The dark sky table shows the Pacific Daylight Saving Time (PDT) times and Pacific Standard Time (PST) times for sunset, astronomical twilight ends, astronomical twilight starts, sunrise, moonrise, moonset and total moon-free, twilight-free viewing time for Portland, Oregon, U.S.A.
