Fragment F Impact on Jupiter

I observed the impact remnants of fragment F of SL9. The observation
was at 02:30 UT from Orlando, FL. The instrument used was a 17.5"
Newtonian, with a Nagler 9mm eyepiece (240x) and a #80A light blue
filter. Transparency was good to excellent, with little atmospheric
disturbances

I noticed a dark marking in the STB. This feature was darker than any
other on Jupiter, including the Red Spot and the main equatorial belt.
If anyone else noticed a similar marking, I would be interested in
comparing notes.
