Gaia-Groundbased Observational Service for Asteroids (Gaia-GOSA) is an interactive tool aiming to facilitate asteroid observers in contributing to the Gaia mission (European Space Agency) by gathering lightcurves of selected targets. GOSA users can plan their observing runs by selecting the visible targets for a given date, collaborate with other observers and upload the frames obtained. OA UAM team is responsible for analyzing the data, publishing the results in the website and creating a lightcurve catalog. Once calibrated, lightcurves will be easily included in the analysis of Gaia data, which will allow to enhance the determination of asteroids’ physical properties.

On the Interactive Service for Asteroid Models (ISAM) webpage, one can choose a polyhedral asteroid model and display its orientation for any requested date and in different modes, including stereoscopic views. One can also generate animations, both for the rotating model and the resulting lightcurve. Making predictions for the future light variations and object orientations is also possible. The latter is particularly useful in preparation of resolved observations such as stellar occultations or adaptive optics.

Asteroid Spin Vector Database
Last updated on 2014-02-14

Originally created by Per Magnusson, at that time working at the Uppsala Observatory (Sweden), is currently maintained by Agnieszka Kryszczyńska. It provides data on asteroid spin vectors (given as the geocentric, ecliptic pole coordinates) and, in many cases, sidereal periods of rotation and shapes.

The database is available in 3 files:

The main table (PostScript or PDF)
A documentation (ASCII file)
A reference list (ASCII file)

If you would rather access the source files, used to create the table, please get one of the packages:

spin.tgz (tar gzipped files for UNIX)
spin.zip (zipped files MS Windows)

After unpacking in a single directory you would get the following files: spin.tex, def.tex, note.tex, newtable.tex, ebdtable.tex, spin.dat. If you have TeX installed, you can then launch the command tex spin.tex and get the spin.dvi which can be converted to other formats like PostScript or PDF.

Please use the following citation to reference this data set: Kryszczynska A., La Spina A., Paolicchi P., Harris A.W., Breiter S., Pravec P., 2007, New findings on asteroid spin-vector distributions, Icarus 192, 223-237.

Former updates are available here.

We are woking on an update and new interface to the database

IAU MDC Meteor Showers Database

Meteor Showers Database is maintained by Meteor Database Center (MDC) of International Astronomical Union (IAU). It contains information about names, radiants, velocities and orbital elements of more than 500 meteoroid showers.
