Attached is a map of the Seattle, WA sky, for 1 October 2018 at 09:00 pm, local Daylight Savings Time. The middle line is your horizon; notice the compass points along it. You are looking southwest in this partial view. The shaded green area below this line shows the stars that are below the horizon.. The curved yellow line is the path of the sun (called the ecliptic) against the background of the sky, marked with the months the sun is at that location. Note that the sun is "in" the September range, close to the Autumnal Equinox. The nearly circular white line is the celestial equator. Points along this line are marked at the boundaries of the diagram in hours of right ascension. The sun is near 12 hours of right ascension at the autumnal equinox, half-way around the sky from its 0 hour position at the vernal equinox.
Using the map as a starting point, choose a clear night at a reasonably light-free location, begin observing as soon as it is dark enough, and try to locate the following objects:
There is no formal data analysis for this observation.
