Optical narrow-band CCD imaging (407nm-907nm) from the 1-m Jacobus
Kapteyn telescope on La Palma shows the impact site of fragment G
remaining prominent between the start of observations at 20:27 UT
until it passed over the Western Limb at approximately 22:17 UT.
Impact site H was well resolved on the Eastern terminator at 20:27 UT, and remained in view until Jupiter set. It appears to have a similar morphology to impact site A as first imaged by HST, comprising at blue wavelengths of a dark center with a crescent to the South-West, but is only approximately half as large as impact site G.
A 3rd impact site, presumable E, is visible on the Morning terminator at 22:08 UT and images thereafter.
