Lowell Observatory offers these tools to assist with asteroid observation planning. The orbital solutions used within these tools are independently calculated from Minor Planet Center observations. Asteroid.lowell.edu is in the process of upgrading and in a Beta status. Functionality should generally be available. However, some tools may experience bugs. If a bug is particularly important, please direct concerns to email@example.com.

|November, 27, 2015||Fixed issue with negative phase angle object being improperly filtered on UpObjecs page|
|November, 18, 2015||Asteph object identifier links bring to prepopulated ephemeris page|
|November, 03, 2015||Fixed Asteph ephemerides. They used to be wrong. Now they are correct.|
