Galactic plane crossing at l = 49.1 on 17 June close to the strong source W51.
Strong continuum background on 18 to 21 June. Galactic confusion.
No 1665 MHz (left) spectrum from 14 to 19 June due to back-end failure.
Close approach to Earth on 9 August 2008 at 0.35 AU.
Doubtful intensity calibration from 17 to 29 July.
