Status • Both A & B instruments continue to function nominally
– No unexpected resets or anomalies – No trend changes in HK health and safety parameters
• S/WAVES operations go well – Commands go up – Telemetry comes down – reduced to rate C – recently gappy – Associated data products are produced and made available – APL operations team continues to get us our bits – thanks!

• what is the typical type III beam width near 1 AU for simple type III bursts?, ! - for multiple type III bursts?, ! - for intense, complex type IIIs (SAs), involving CMEs?!
Unique Science Questions:!
Spatial extent of the electron beam !
Radiation characteristic of the electron beam!
Exciter speeds within the beam!
• how are in-situ LWs and local emissions near 1 AU distributed ! longitudinally and radially within the electron beam?!
I Analysis of In-situ signatures of Type III electron beams:!
• do the type III exciters decelerate as they propagate through the IPM to 1 AU?!
• what is the spatial range of the local emissions observed near 1 AU?!
• is there an exciter speed variation across the beam?!
• how do the intensities and durations of LWs and local emissions vary! at different spatial locations within the electron beam?,! - with plasma & magnetic field parameters?! - with exciter speeds?!
• how often are local emissions and LWs observed simultaneously near 1 AU?!
As the angular separation between the STEREO s/c decreases during the 2014 – 2016 time frame!new and unique observations of the electron exciter beam characteristics for solar type III bursts!
and for in-situ type II radiation can be made!
• can we directly measure, by time-of-flight, the exciter speeds near 1 AU!where in-situ plasma waves analyses are generally done and where theories are tested?!
• when both STEREOs observe local emissions, will this radiation in the type III!source region have the same harmonic structure?,!
- will the TDS waveforms exhibit the same harmonic structure?!

• how are type II source foreshock regions distributed over the shock front near 1 AU?!
II Analysis of In-situ signatures of radiation generated by CME/shocks:!
• how long does a typical type II foreshock region generate radio emissions?!
• how does the local type II radio intensity vary with shock location and !geometry (quasi-perp vs. quasi-parallel)?!
• how often are signatures of locally generated type II emissions near 1 AU observed? !
• why is remote type II radiation sometimes observed only at the !fundamental of the plasma frequency, !
other times only at the harmonic, and sometimes at both?!
• what is the spatial extent of a type II foreshock source region at the shock front near 1 AU?!
• how does the local type II intensity vary with the !plasma and magnetic field parameters?!

Behind the Sun Current Sheet (CS) Observations Between STEREO A and B at 1 AU
Fundamental question: Are small- and large-scale CS fundamentally different? (turbulent-driven vs. flux tubes representative of solar magnetic field origins?)

Reduced operations • S/WAVES normally uses 1 packet per second
– 58 packets/minute of science by default (2,104 b/s) • Reduced as we move away
– Rate A: 2,104 – Rate B: 1,897 – Rate C: 1,674
– 1 packet per minute of HK (36 b/s) – 1 packet per minute of SWX (36 b/s)
• Reduced science can be done with HK and SWX alone
• Some science with ~3 hours per day • Better science with A-B overlap
• Magnetic field vectors would be good too

Behind the Sun • S/WAVES could do some good science
– Luck might give us some great stuff • We have not done a lot of power-ons in the blind
– Would likely work perfectly well • We do not have an internal non-volatile stored command table • We could build and upload a flight software patch
– Giving desired behind-the-sun mode and bit-rate by default – Telecommands – when available – would allow a return to normal mode – Writing to S/C SSR partition – FSW development is more or less straight forward but not funded
• Giving us great recorded far-side science • IMPACT
– MAG would be very useful – STE suprathermal electrons would be very useful
