Using vocabulary such as meridian, zenith, etc., describe the relationship of a star's altitude above the horizon and the observer's latitude. if you are positioned at the earth's equator, and a given star is at your zenith, what happens to that star's position (relative to you, the observer) as you walk in a straight line to the north pole? why are some stars and constellations only seen during certain seasons?

An. observer is at latitude 40 degrees north. his siderea teafa star clock reads 12h @m; he wishes to secure observations of as whose declination and right ascenston are degrees and bhoom respectively. draw a celestial hemisphere showing the orientatio of the sky, and the position of the star, at the instant ol observation. in your diagram, be sure to indicate (a) the relevant compass points (b) the visible celestial pole (c) the celestial equator (d) the relevant hour circles. from your diagram, compute the hour angle of the star at the time of observation. 2. as in question 1, draw celestial hemispheres indicating the orientation of the sky for the following scenarios: (a) latitude of observer: 40 deg i sidereal time: 06h00m declination of star to be observed: deg ra of star to be observed: lhom indicate the position of the star on your hemisphere. (b) latitude of observer: 40 deg n sidereal time: 18hom ra of star to be observed: 12hoom dec of star to be observed: +30 deg indicate the position of the star on your hemisphere. 3. an observer is at 40 degrees north latitude. given the following data, in the missing blanks, and then carefully draw an appropriate representation of the sky for the data. clearly indicating the position of the star in each case: (1) ra of star: [ ? ] dec of star: +6% degrees st: first point of aries in upper transit ha: +3h (11) ra of star: 23 h dec of star: -20 deg ha: -2hom hour angle of first point of aries (fpoa): [ ? ] (111) ra of star: 05h30m star on, celestial equator. st: @2h33m ha: [ ? ] (iv) ra of star: [ ? ] dec of star: +45 degrees hour angle of fpoa: 05h45m hour angle of star: -06
