If you look at a two week section ending today you can see the effects of the magnetosphere's bow shock from entering the stream on middle of July 5th, and exiting on the 12th.

I Googled some of the satellites you mentioned, and was not able to find a source of current data, in a format I could figure out fast enough to respond in a timely manner.
Basically what you are seeing here are substorm signatures, created by reconnection in the magnetotail, which happen every few hours. However, not all of these can be seen by one station, because they happen at the night side of the Earth.

This was created by the southward turning of the solar wind magnetic field on the 5th. And basically, every time the red line (Bz) goes below zero you will find such signatures in the ground magnetometers.

The SWEPAM data show a normal density, with an increase of the solar wind speed by ~50 km/s and then a return again to long time average solar wind speed of 350 km/s and normal variations of the density. I do no see why this should imply a "concentrated ion stream".

It does look like (edumacated guess) that on the 12th there was the passage of a flux tube (looking at the magnetic field data), but theses also pass by when Jupiter is not aligned with the Sun-Earth line, so I fail to see the significance.
