*Question E2A01:
What is the direction of an ascending pass for an amateur satellite?*  

*Correct Answer is  C: From south to north*  

### AI Response: (may contain errors)  

The correct answer to the question about the direction of an ascending pass for an amateur satellite is:

**From south to north.**

### Explanation:

1. **Why the correct answer is correct:**
   - An ascending pass refers to the moment when a satellite moves from being below the horizon to above it. For satellites in low Earth orbit (LEO), which are commonly used in amateur radio, they typically travel in a northward direction as they ascend. This is due to the inclination of their orbits, which are often designed to cover a wide area of the Earth, including regions in the southern hemisphere.

2. **Why the other choices are incorrect:**
   - **A: From west to east**: This describes the general direction of the Earth's rotation and is not specific to the ascending pass of a satellite.
   - **B: From east to west**: This is the opposite of the typical direction of satellite movement and does not represent an ascending pass.
   - **C: From south to north**: This is the correct answer, as explained above.
   - **D: From north to south**: This describes a descending pass, where the satellite moves from above the horizon back down to below it.

### Useful Rules of Thumb:
- **Satellite Orbits**: Most amateur satellites are in orbits that allow them to cover a wide area, often with inclinations that lead to ascending passes from south to north.
- **Tracking Satellites**: When tracking satellites, remember that they will rise from the horizon in the direction of their ascending path, which is typically south to north for many amateur satellites.
