Welcome to MinorPlanet.Info
This web site serves as a gateway to the Collaborative Asteroid Lightcurve Link (CALL) web site in addition to many other subsites, external sites, and pages that concern research on asteroids (the "minor planets").
Use the links at left to navigate to the subsites.
Expanded Features on Observing Planning Tools
The Ephemeris Generator and One Asteroid tools (available via the Observation Planning page) now use a single oppositions data table that covers from 2014-2019. This allows you to plan further into the future. The table will be updated around the first of each year, removing the oldest data and extending out another year.
2015 Appulse Data Available
The Observing Guides page has links to asteroid-DSO/PPM/asteroid appulses for 2015.
Collaborative Asteroid Lightcurve Link (CALL)
The CALL web site provides pages to where you can "reserve" an asteroid for observation. This lets other observers know that you are working it and either find another target or to request a collaboration in order to gather more data sooner. You can also submit the results of your asteroid lightcurve observations so that they are available to others prior to formal publication. The CALL site includes subpages that provide lists of targets for upcoming and recent past 3-month periods and other sites dedicated to asteroid lightcurve efforts.
The Minor Planet Bulletin
The Minor Planet Bulletin is the journal for amateurs (and even professionals) to publish individual lightcurves (one at a time or in bulk). The Bulletin is indexed by the ADS and found in the libraries of major observatories and institutions around the world. Since the early 21st century, the MPB has published the vast majority of new asteroid lightcurves.
The Asteroid Lightcurve Database (LCDB)
The asteroid lightcurve database (LCDB; Warner et al., 2009, Icarus 202, 134-146) is a compilation of published results that now includes period/amplitude parameters for more than 4,000 asteroids. In addition to a ZIP file download that contains pre-generated files, the LCDB pages include a query page where you can generate custom reports.
