H2 S(1) in impact E

Spectroscopical separation of E & F sites

After further analysis of our IRSPEC-NTT spectra of impacts E and F (July 18, 2:30 UT) centered at 2.12 microns along the parallel of the impact sites we now believe that we are able to distinguish between the two impact regions.

The spectrum of impact F is characterized by a featureless continuum (which, if thermal, indicates temperatures of ~1000K), whereas the already evolved site E shows little continuum, but strong H2 S(1) line emission.
