It had been thought that the details of the "Field Day" evening 2-m Es event would be the dominant feature of my presentation. However, a near-equally intense 144-MHz Es opening occurred July 24! (Too close to the Conference to prepare any similar in-depth analysis.)

Note that most, but not all, of the 144-MHz events occurred during the days with the highest amount of 88-108 MHz Es. For a stack-plot graph of this data.
