| Service Name | Short Name | Description |
|---|---|---|
| Hierarchical Observation Protocol | HOP | Generate an observationally prioritized list of asteroids based on the capabilities of the user's instrument and other generic requirements. |
| Critical List of Asteroids | CRITLIST | View a pre-selected list of asteroids in need of observation. |
| Minimum Orbital Intersection Distance | MOID | View a list of asteroids whose orbits are very near the orbit of one or more of the major planets. These asteroids can have rapidly changing orbits due to perturbations by the large planets. |
| LONEOS Observations | LONEOS_OBS | View lists LONEOS asteroid observations. |
| Service Name | Short Name | Description |
|---|---|---|
| Asteroid Ephemeris | ASTEPH | Generate an asteroid ephemeris by selecting the asteroid by name, the start time, duration and interval. |
| Asteroid Observability Chart | OBS | Build a chart which indicates when an asteroid is observable. The observability calculation is based on the user's instrument, and location and the asteroid's declination, uncertainty, solar elongation, magnitude, and galactic latitude. |
| Asteroid Observing Strategy | OBSSTRAT | Calculate the dates for a "small" number of observations that will result in the numbering of an asteroid. The calculation is based on the user's instrument and location. Build a chart showing the ephemeris uncertainty after each suggested observation. |
| Asteroid Finder Chart | ASTFINDER | Build a chart showing the position of a selected asteroid and the surrounding stars. The motion vector and the line of variation are indicated. |
| Asteroid Plot | ASTPLOT | Build a plot that depicts the position of stars and asteroids within a defined region. |
| Service Name | Short Name | Description |
|---|---|---|
| Asteroid Orbital Elements | ASTORB | View a list of asteroid orbital parameters and physical properties. The orbital parameters are updated daily. |
| USNO-A2.0 Star Catalog | REFNET | Create a list of stars that meet various positional and brightness criteria. The base catalogs include USNO-A2.0, USNO-SA2.0, and PPM. |
| Service Name | Short Name | Description |
|---|---|---|
| Lowell Observatory Near-Earth Object Search | LONEOS | View a description of the LONEOS project. |
