Seasonal Position of Constellations,<br />

Activity 5-5<br />

Objective<br />

The student should be able to describe the relative positions of the circumpolar stars<br />

in different seasons of the year.<br />

Background<br />

If the circumpolar constellations are observed at the same time each night throughout<br />

the year, they will appear to make a complete rotation around Polaris (North Star).<br />

Procedure<br />

• Use the Do it Yourself Starfinder to become familiar with the position of the<br />

circumpolar constellations in various months of the year.<br />

• Have the Starfield Cylinder set for one of the fall months. Make your observation<br />

time about 9:00 p.m. for your latitude.<br />

• To show students the different positions of the circumpolar constellations throughout<br />

the year, simply rotate the projector month-by-month past the<br />

9:00 p.m. observing time as indicated on the hour and date scale.<br />
