We communicate the non-detection of flash from fragment L on Europa from
Pico-dos-Dias Observatory. Europa was monitored with a rapid photometer
binned on 0.1s. in the V-filter from 21:32:54UT until 22:27:51UT. Ath`
22:23:45UT was noticed an extremely bright plume on the limb of
Jupiter. It increased in intensity from 22:23:45UT until 22:27:51UT
when it began to fade away.
In raw data appeared a very strange, unexplained and symmetrical decrease
in intensity around 22:14:06UT by nearly 20% of mean intensity.
Furthermore we report the non-detection of the B and F impact flashes
as well.
CCD spectroscopy and direct imaging of plume were also performed. Data are being analysed.
