Are you a professional or a motivated amateur astronomer? Do you have access to a professional astronomical observatory or you have your own astronomical equipment along with a CCD camera? Then, this project suits you perfectly. In order to get involved in our project follow the instructions and guidelines, perform the desired observations, submit your data and contribute in the Ancient Asteroids project.
The asteroids, that are going to be observed, are quite faint and therefore serious equipment is required in order to achieve high signal-to-noise (S/N) ratio. Please, see the below the minimum requirements that are eligible to allow you getting involved in our project.
Minimum instrumental requirements:
The purpose of the campaign is to collect photometric observations in optical wavelengths, of asteroids that belong to old collisional families. The observations will be used to produce light curves (see Figure below), which are the results of the asteroid's rotational and morphological properties.
The rotation of an irregular 3D object, causes different areas to reflect sunlight towards the observer. This results in variable brightness of the observed object. Careful analysis of the periodicity, amplitude and light curve shape reveals the rotational and morphological characteristics of asteroids.
In order to perform valuable and useful data for our project, please follow the observing quidelines strictly.
A sample of light curves are listed below, so as to give an idea of the results we expect to extract out of our observational campaign.

All targets for the project are displayed in the List of Primordial Family members. In order you to find which of these asteroids are observable during your observation period from your location, we are highly recommend to use the online Web Application The application will also provide the observation plan for your selected target. The ephemerides of asteroids can be also calculated through MPC Ephemeris Service or JPL's HORIZON system.
Observations are accepted from professional and amateur astronomers, who actively collaborate with University of Athens faculty members
and wish to be partners in Ancient Asteroids Project.
Electronic submission of the observations is required. This involves uploading your image and calibration files in .fits (.fits, .fts or .fits), following the instructions given below.
Applicants are required to consult the relevant "Observing Guidelines" webpage when preparing their observation plan. Usually, an observation plan includes several hours of data collection with specific requirements, that all observers should follow, in order to produce useful data in our project. Make sure to follow all instructions given below and use the provided online tools for contacting us and for praparing your observation plan. These are required to proper refer to you as a collaborator and use your data in our project. Not following the exact steps may cause your files to be lost, not properly processed and eventually not used in the project.
In order to submit your observations, we first need to know a few things about you. We kindly ask you to fill the online PERSONAL INFORMATION FORM. Instructions for filling the Personal Information Form can be found here.
Your contribution, personal information and data files will be received by the members of the Data Processing and Analysis Consortium (DPAC).
The observations will be evaluated and will be further proccessed, in order to be included for analysis.
