We used the 1 meter telescope at the Vainu Bappu Observatory and obtained images on 18th and 19th through narrow and medium (100 A) pass band filters (8930 NB, 8900 BP, 6581, 5083, 4935 and 4862 A). The crash spots and the south pole appear very bright in the methane band at 8930. The crash spots appear dark with good contrast in the other filters. At the 2.34 meter telescope long slit spectra in the region 4900 - 7400 A of the crash latitude were taken. No obvious changes in the spectrum at the crash spot is immediately apparent. More detailed analysis will be required to detect small changes.
