1) You are at the Tropic of Capricorn (23.5 degrees South latitude), on the summer solstice at mid- day when the Sun is highest in the sky. A) What is the altitude of the Sun at this time in degrees? B) Describe the length of the shadow of a tall flagpole at this time and date? C) Melbourne is at latitude 28 degrees North. Will there ever be a day when the flagpole's shadow disappears? Briefly justify your answers.

On November 21 at a location in the Northern Hemisphere, the sunrise was at 7:25 A.M.  and sunset was at 4:25 P.M.  On December 21,  the sunrise was at 8:00 A.M.  and the sunset at 4:20 P.M.  What was the average change in daylight per day,  in minutes, during this month? (Assume all times are standard time.) average daylight change = min   day

H3. A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur. How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur? Show the algebraic solution, any information you use.

In astronomy what does it mean when asked about the altitude when it comes to the moon?
