Descripción
The ESO/MPG WFI and the INT WFC wide field archives comprising 330 000
images were mined to search for serendipitous encounters of known Near
Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A
total of 152 asteroids (44 PHAs and 108 other NEAs) were identified
using the PRECOVERY software, their astrometry being measured on 761
images and sent to the Minor Planet Centre. Both recoveries and
precoveries were reported, including prolonged orbital arcs for 18
precovered objects and 10 recoveries. We analyze all new opposition data
by comparing the orbits fitted before and after including our
contributions. We conclude the paper presenting "Mega-Precovery", a
new online service focused on data mining of many instrument archives
simultaneously for one or a few given asteroids. A total of 28
instrument archives have been made available for mining using this tool,
adding together about 2.5 million images forming the "Mega-Archive".
Using ESO/MPG WFI images served by the ESO Science Archive Facility and
INT WFC images served by the CASU Astronomical Data Centre.

Este Proyecto estudia las propiedades físicas y composicionales de los llamados pequeños cuerpos del Sistema Solar, que incluyen asteroides, objetos helados y cometas. Entre los grupos de mayor interés destacan los objetos trans-neptunianos (TNOs), incluyendo los objetos más lejanos detectados hasta la fecha (Extreme-TNOs o ETNOs); los cometas, y
