Today, on all Probes the Instrument Data Processors, FluxGate Magnetometers and ESA Low Voltage Power Supplies were turned on and checked out. All systems were nominal in current and temperature. FGM sensor data recording began and we should see the first science data play out in the next orbit.

Probe A was rolled so that the sun is on its side-panels rather than on its top. This will cool the top down.

All five probes are in very good health. Temperatures are very mild on the probes now in their nominal attitude with sun on their side panels. Engineers are finalizing data collection and analysis on two technical items at this time. The first item involved the occasional false over-voltage trips in charging circuits and the second involved measuring the command and telemetry link performance.

Communications with the probes have improved greatly due to better orbit and attitude information. For example, last night we had successful telemetry at 64 KHz at a distance of over 50000 km using Probe A
