the japanese ir sky survey mission irts (infrared telescope in space) was performed successfully in 1995. the irts data are now beeing analized. to date, we have obtained the intensity maps of the so-called uir emission bands at 3.3, 6.2, 7.7, 8.6 and 11.3 micron in the galactic plane at around l=50 deg. the diffuse component emissted from the general interstellar space without any strong uv sources has been clearly detected in those maps. the spectral resolution of the irts, however, was 20-30, a little bit too low for an accurate estimation of each uir band. therefore, follow-on observations of the part of the sky area surveyed by the irts with a higer spectral resolution are very valuable. and to check for the consistensy between the irts and the iso is also important for both missions. we propose here the spectrophotometric observations of the diffuse uir band in the galactic plane region near l=50 deg with the pht-s.

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.
