Nancy, Somebody from tt-france had access to the Haute-Provence Observatory in France (a professional one) and he had the opportunity to point to the co-ordinates you indicated. Please have a look at the photos. Here are the technical details: The first attached photo ( provided by ESO Digital Sky Survey) includes the comparison field (one must do inverse-rotation to compare) The 4 other ones are the images he took on Jan, 19 2002. using a 5'x5' field centered on the co-ordinates given by the Zetas on Jan, 17 2002: RA = 4h 27mn 22s Dec = 12h 8mn 20s. The two circled objects are the only two objects which do not exist in the reference field. Best regards, Véronique
