Spots at the sites of impacts K, G, H, F, E, A, and C were observed by Kaz
Sekiguchi and Brian Carter using the PtSi infrared camera and 0.75 m telescope
for imaging at 2.2 microns (K). Spot C is surrounded by a large dark ring. All
these spots still appear bright at this wavelength, with C the least intense
and G the brightest. Jupiter images were obtained covering the period when
Jupiter was sufficiently high in the sky. The PtSi camera was developed at SAAO
by Ian Glass in collaboration with the National Astronomical Observatory of
Japan and the University of Tokyo, using a Mitsubishi chip.
Peter Martinez of the University of Cape Town used the 0.5 m telescope for high speed photometry in U of the disk of Jupiter. The airmass was rather high, and it is not certain whether the impact of fragment L was detected.
