The Stars Observation - Assignment Example

The pattern of Ursa Minor had changed the same as its position; it is almost at the meridian line and slightly below (Hale, Pp. 58-60). Ursa Major has also moved downwards and has crossed the meridian and its pattern has also changed. There is an unnoticeable change after ten minutes repeat of the observation (Hale, p. 60). Less change could be recorded after ten minutes. From these observations, we can conclude that Polaris is always on the meridian and is a star that never sets and can always be seen throughout the day and night at the same position. Also Ursa Minor and major rotate as the sky rotates and will set at some point and cannot be seen throughout the day and night (Hale, p. 59).

The nest observation was at 02: 29. Star Polaris had not changed its position but remained on the meridian line. It is acting as the tilt point of Ursa Minor. However, less change has been observed with Ursa Minor (Pasachoff and Filippenko, p. 80). Its position has changed a bit as it is on the meridian line but the pattern has not changed. On the contrary, Ursa Major is also changing in its position but the pattern has remained the same (Hale, p. 60). It is slowly approaching the west side and still, the same stars seen in its pattern at the beginning of the observation could be seen which are Mizar, Alkali, and Dub he (Pasachoff and Filippenko, p. 82).
