Carlos Amaya ASTR101 Ivy Tech Community College 3/20/2024 Name: Carlos Amaya Lab 2: Moon Phases Objective: Determine the relationship between the positions of the Earth, Moon, and Sun over several observations. Procedure: 1. Before the lab deadline, observe the Moon on at least 5 different days. 2. For each observation, make a sketch on the lab sheet showing how the Moon appears in the sky and label it with the name of the phase. 3. For each observation, record the date and time of day (including am or pm), as well as the number of days since the previous observation. 4. For each observation, describe approximately where in the sky the Moon is located. (For example, “low in the sky in the southeast”, “on the western horizon”, or “high in the sky towards the south”.) Also give a basic description of any features visible on the Moon and note any changes from previous observations. 5. For each observation, include additional notes that are relevant or of interest (weather conditions, apparent size in the sky, etc.). 6. For each observation, place the Moon on the diagram in the appropriate location and label it with the date of the observation. 7. Study the sketches, notes, and diagrams you have completed and then answer the questions at the end of the lab. Sketch Date/Time Location Notes Date: 4/08/2024 Time: 2:31PM Location in Sky: Directly in front of the Sun Features: Full Moon Other Notes: Rays of the sun still visible when moon completely covered the sun! Phase: New Moon

Carlos Amaya ASTR101 Ivy Tech Community College 3/20/2024 Sketch Date/Time Location Notes Eclipse Date: 4/13/2024 Time: 9:47PM # Days Since Previous Observation: 5 Location in Sky: Facing West in front of the sun Features: Slight appearance of the moon Other Notes: stars are not really visible Date: 4/14/2024 Time: 10:12PM # Days Since Previous Observation: 1 Location in Sky: Facing West heading east in front of the sun Features: almost at half moon Other Notes: Date: 4/18/2024 Time: 9:38PM # Days Since Previous Observation: 4 Location in Sky: Facing eastward of the sun Features: Nearing Full moon Other Notes: looks like cheese! Date: 4/19/2024 Time: 10:47PM # Days Since Previous Observation: 1 Location in Sky: facing east of the sun and heading west Features: Almost at full moon Other Notes: Phase: Waxing Crescent Phase: Waxing Crescent Phase: Waxing Gibbous Phase: Waxing Gibbous

Carlos Amaya ASTR101 Ivy Tech Community College 3/20/2024 Questions 1. What was the total length of your observations (i.e., how many days between the first and last observations)? 11 Days Total 2. Over the total time of your observations, describe how the appearance of the Moon changed (be specific). From the crescent moon to the waxing gibbous, the amount of the moon that was visible was so little it almost looked as if the moon wasn’t there. The Waxing gibbous on the other hand, especially on my last day of observation, almost displayed like a full moon. 3. With references to your observation notes and the diagram you completed, explain how the location of the Moon relative to Earth and the Sun are related to what you observed. During the total eclipse, the Moon lines up perfectly between Earth and the Sun, creating a shadow on Earth during the new moon phase. The Waxing crescent moons I saw showed those thin slivers we see in the western sky after sunset, getting bigger each night. They start with the lit part on the right side (for folks in the northern hemisphere).
