“…To plan our runs and select program NEAs given an observing place and date, we used two planning tools (EURONEAR, 2012b) which target the newly discovered objects from the Spaceguard priority list (Spaceguard, 2012) and the NEA bright and faint recovery opportunity lists maintained by the Minor Planet Center (MPC, 2012a). More information about these planning tools can be found in Vaduvescu et al (2011).…”

“…For relatively sparse observations and small sky area covered, Astrometrica has been proven an excellent team capability for use by students and amateurs. Moreover, for limited amounts of data, the human eye and brain have been better for moving object detection, reaching lower S/N detection versus automated pipelines (see for example Vaduvescu et al (2011) for some references and comparison).…”

“…Adding the 477 observed NEAs to our previous work presented in Birlan et al (2010a) and Vaduvescu et al (2011), we report a total of 739 NEAs observed within the EURONEAR network during the last six years. The reduced data presented in this paper generated 98 MPC publications, comprising 69 Minor Planet Circulars (MPC) and 29 Minor Planet Electronic Circulars (MPEC).…”

“…Vaduvescu et al (2008) introduced EURONEAR and first observations obtained at Pic du Midi in 2006, followed by Birlan et al (2010a) who described the first 160 observed NEAs using nine telescopes available to the EURONEAR network during the first four years. Vaduvescu et al (2011) presented some MBA and NEA statistics based on three runs using large field 1-2m facilities (Swope 1m, ESO/MPG 2.2m and INT 2.5m).…”

“…Thanks to two observing runs and a few discretionary time hours awarded to use the large field imaging cameras of the 2.5m Isaac Newton Telescope (INT) and Blanco 4m telescope, in a team comprised mostly of students and amateur astronomers we obtained and carefully analyzed 572 CCD fields covering 34 square degrees, visually scanning, measuring and reporting around 12 thousand positions of more than two thousand asteroids. We have then used the data obtained with 2-4m telescopes to derive MBA and NEA statistics going beyond our previous results based on data obtained with 1-2m facilities (Vaduvescu et al, 2011).…”

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.

Precovery of near‐Earth asteroids by a citizen‐science project of the Spanish Virtual Observatory

et al. 2014

This article describes a citizen-science project conducted by the Spanish Virtual Observatory (SVO) to improve the orbits of near-Earth asteroids (NEAs) using data from astronomical archives. The list of NEAs maintained at the Minor Planet Center (MPC) is checked daily to identify new objects or changes in the orbital parameters of already catalogued objects. Using NEODyS we compute the position and magnitude of these objects at the observing epochs of the 938 046 images comprising the Eigth Data Release of the Sloan Digitised Sky Survey (SDSS). If the object lies within the image boundaries and the magnitude is brighter than the limiting magnitude, then the associated image is visually inspected by the project's collaborators (the citizens) to confirm or discard the presence of the NEA. If confirmed, accurate coordinates and, sometimes, magnitudes are submitted to the MPC. Using this methodology, 3,226 registered users have made during the first fifteen months of the project more than 167,000 measurements which have improved the orbital elements of 551 NEAs (6% of the total number of this type of asteroids). Even more remarkable is the fact that these results have been obtained at zero cost to telescope time as NEAs were serendipitously observed while the survey was being carried out. This demonstrates the enormous scientific potential hidden in astronomical archives. The great reception of the project as well as the results obtained makes it a valuable and reliable tool for improving the orbital parameters of near-Earth asteroids.
