===================================================================== ==> in this proposal, more time is being requested for obsid.propid ==> time for this proposal is to be transferred from obsid.propid ==> this proposal requests an upgrade from priority 3 for obsid.propid ===================================================================== the star forming region around iras 05487+0255 encloses at least three stellar jets which have some peculiar properties. two of the jets are not detected at optical wavelengths, but only in the near infrared (2 micron) in molecular hydrogen. the brightest jet in the region is detected in halpha, sii 6731 and the molecular hydrogen lines, but its source either is more than 100 arcseconds away or has not been detected. indeed to explain the turbulent optical morphology of hh 110 it has been suggested that the gas outflow originates farther away and that it is undergoing a grazing collision with a molecular cloud. finally, the source for one of the molecular hydrogen jets seems to be misplaced, given the low spatial iras resolution, and is invisible in the k band. the goal of this project is to map the iras 05487+0255 region using isocam to discover the true source of the hh 110 jet and the nature of the iras emission. maps will also be performed for the molecular hydrogen emission to determine its relationshp with the nearby sources. two raster maps will be performed using a pfov of three arcseconds. one 2x2 map for two broad band filters, and another 3x3 map for two narrow band filters. the experiment is designed to detect sources ten times fainter than iras 05487+0255 in its neighborhood, and to map the molecular hydrogen emission. the total time including overheads for this observation is 2725secs.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
