Observational report from the Zelenchuk observing team:

Belgo-Franco-Russian team tentatively observed the W impact between 1900 and 1930 UTC using a Fourier spectrometer working from 2400 to 3000 cm-1 at a 0.25 cm-1 resolution. Observations were performed at the SAO 6-m telescope located in North Caucasus. A CCD camera provided impact and spot monitoring. The intense spot at the site of impact W was observed 11 hours after crash. It is not easily separated from those of U and K. Its general shape is seen as a diffuse circular dark spot as large as 3.5 arcseconds. The reduction of spectral data will be made later. Unfortunately, bad weather prevented other observations at this date except on July 19.
