From
Flightradar24.com - Live flight tracker! there is an ADS-B data file with 7909 data points available.
Final position is N44.234 E006.407 at 09:40:36Z, FL68, VS -3520 ft/min
The data file needs to be filtered for several stations that deliver bad data etc. The best station is 1418 which sends consistent data which data is plotted below
.
There was no change of squawk (5512 all the time).
FL380 was maintained for exactly 3 minutes before it was left again.
The descent was initially shallow, it did not start abrupt.
Here is a plot of Vertical rate and FL over Latitude. Track was 025° over the entire plot and GS was only slowly decreasing, therefore Latitude is almost proportional with time.
Vertical speed is fluctuating quite significant.
At the time of start of descent track changes 20 degrees to the left, but this seems to be in line with the flight path (same as day before).
