Antenna: 8 element wire Log Periodic
Software: Modified version of the Radio-Sky Publishing Spectrograph software.
Times are in UTC. This was was a marginal pass through the Io-A region and it was surprising that even these few extremely weak bursts were captured. The graph below is a screenshot of of the Radio-Jupiter Pro CML - Io Phase graph showing the pass. The actual period of observing was from 13:30 to 15:30 UT. Only periods of noticeable activity are presented here.

The first tiny hint of activity is seen at 13:52 below 19 MHz.
Very weak activity is seen here about 14:12.
The last activity was detected about 14:20 in the 22 to 23 MHz region.
