5. Stellar observation showed a star with zenith distance equal to 2317' on 09 February 2006. Using the Philippine Geodetic Almanac, determine the correct altitude of the star if the initial horizontal reading was 1113'.

6. If the value of the NPD at 8:00AM of 06 April 1997 is 7200'03.31" with hourly variation of +36.02", the NPD of the sun on 06 April 1997 at 8:41AM is:

7. From the following data, determine the latitude of place of observation. The star observed is Polaris as it attains its upper culmination. Altitude of Polaris at U=4337', Index Error =-30", and Declination =+ 8844'35".

8. A star has an hour angle of 3411' and an azimuth of 20317". The star's declination during the observation is -4742'. Altitude of the star at the place of observation is:
