Abstract

An ASCA observation of the Jovian impact of the comet Shoemaker-Levy 9 is reported. Four impacts of H, L, Q1 and R were observed and four impacts of B, C, G, and Q2 were observed within 60 minutes after their impacts. No significant flaring of X-ray emission was observed. Upper limit X-ray fluxes of 90 % confidence level, averaged 5 minutes just after the impacts, were 2.4 × 10^-13 erg sec^-1 cm^-2, 3.5 × 10^-13 erg sec^-1 cm^-2, 1.6 × 10^-13 erg sec^-1 cm^-2 and 2.9 × 10^-13 erg sec^-1 cm^-2 for the impacts of H, L, Q1 and R, respectively, in the 0.5(0.7 for H and Q1)-10 keV energy range. However, a hint of X-ray enhancement around Jupiter from July 17 to July 19 was detected with about 2 ∼ 6 × 10^-14 erg sec^-1 cm^-2 in the 0.5-10 keV energy range.
