Welcome to the Asteroid Lightcurve Database
The Asteroid Lightcurve Database is a listing of asteorid lightcurve parameters and other information, e.g., estimated/measured diameters, absolute magnitudes (H), phase slope parameters (G), albedos, and more.
A summary set of tables is distributed annually for general use along with special versions for the Planetary Data System (PDS), the ITA in St. Petersburg, Russia (Ephemerides of Minor Planets), and the Minor Planet Center.
Click here to download the latest public release (2015 July).
The 2015 July release contains more than 13,500
summary records as a result of two papers using data from the Palomar
Transit Factory. See the updated README.TXT in the ZIP file for more

LCDB References Table with ADS Hyperlinks
Click here to go to the LCDB References page that features BibCode hyperlinks into the NASA/SAO Astrophysical Data System (ADS). In many cases, you can download a copy of the original paper from the ADS page.
LCDB On-line Query Form
The on-line query form retrieves all columns from the LCDB Summary table, limited if you want to those records matching one or more filters. For example, you can limit results to a specific group, size, and/or rotation period.
The on-line query returns a table with a radio button in each row. Select one of the rows and click a button to display all entries tied to the select object from the Details, Ambiguous, Binary, Spin Axis, Tumbling, and Color Index tables.
