Orientation

Point out north, east, south, west, and zenith (highest point directly above). Assign a landmark to each, if possible. If no landmark exists, use a person. Estimate the ‘horizontal coordinates’ of the heavenly bodies using astronomy’s system of ‘altitude and azimuth.’‘Altitude’ measures the angle of an object’s apparent elevation (or curved height) on the celestial sphere (the dome of the sky), relative to the observer. 0° refers to the horizon on a level plain. 90° refers to the zenith. Thus, halfway upward from a flat horizon to the sky's zenith would be 45°. A third would be 30°, two-thirds would be 60°, etc.Many people find that their fist held at arm's length can approximate a space of 10°, or the distance from thumb to pinky of stretched fingers can approximate 20°. Experiment with adding these estimations from horizon to zenith to learn if these can help you. Or look up the known altitude of objects in a chart or app. ‘Azimuth’ measures the cardinal directions (north, east, south, and west) on a scale from 0 to 360 degrees. But simply saying the English direction (e.g. “north-northeast") should suffice. Estimate the brightness of heavenly bodies using astronomy’s system of ‘apparent magnitude’. The ‘magnitude’, or brightness, of stars was first catalogued by ancient Greeks on a scale of one (for the brightest) through six (for the dimmest). In the nineteenth century, modern astronomers formalized the system on a logarithmic scale, extended the scale below one and above six, and set Vega as its zero point (Vega being exceptionally bright; visible in the Northern Hemisphere for most of the year). The word "apparent" was added because it was then realized that brightness depends more on a star's distance from the Earth. A separate measurement called ‘absolute magnitude’ describes the brightness of each star if observed from a standard distance.
