| Description | the level of the moon straylight is assessed during the solar eclipse period in september-october 97. on three subsequent revolutions the telescope is pointed at the same position of the sky, while the moon is approaching from 50 to 28 degrees. influence of the solar straylight is suppressed by the eclipse. any measurable difference from the absolute sky brightness can be attributed to the moon strayligth. in order to calibrate the signal absolutely measurements on a celestial secondary standard are repeated on each revolution. at 170 micron this is the galaxy eso 486-g049. |

| 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. |
