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.
