Minutes

* The SSC presented the baseline plans based on the input from the instrument
  teams.  The baseline plan fits within the allocations, so the only question
  was what extra telemetry should be added to fill out the residual.

* All the instrument teams except SECCHI are recording their beacon telemetry
  on the SSR.  These data also come down during the realtime passes.  The
  actual allocations weren't discussed during the telecon, but appear on the
  spreadsheet conjunction.xls.

* IMPACT presented plans for using the residual telemetry allocations for both
  side lobes 1 and 2.

* It was pointed out that the additional SEPT-NS measurements for side lobe 1
  would be the only ones taken out of the ecliptic.

* Additional SIT event telemetry for side lobe 1 would improve the composition
  measurements.

* IMPACT data would be produced on the same time scales as currently, which is
  SEP data within a few days, and HEP data within a month or two.  Beacon data
  would be processed within the SSC as usual, and would be the data used for
  space weather forecasting.  The other realtime data telemetry would be used
  for after-the-fact data analysis.

* The IMPACT proposals for side lobe 2 cover a wide range of telemetry rates.

* PLASTIC depends on ApID 0x200 from the IMPACT housekeeping.

* PLASTIC would like to see ApID 0x317 to their side lobe 2 telemetry for 2D
  measurements of protons and Helium.  Their calibration monitoring would also
  be improved with these data.

* SECCHI plans to concentrate on EUVI and HI images.  Small COR1/2 images would
  be brought down mainly to monitor the health of the telescopes.

* SECCHI is looking into the possibility of saving some images in their own
  internal RAM to be brought down later during the realtime pass, e.g. with a
  12 hour or even 6 hour separation.

* SECCHI requests an additional 325 bps during side lobe 2 operations to bring
  down improved HI images.  Images were presented showing the improvement in
  the images for several image conditions.

* The baseline SWAVES plan would bring down only the beacon and housekeeping
  packets.  However, during side lobe 1, they would like to bring down an
  additional 10.7 packets/minute (~390 bps).  This would double their frequency
  resolution, approximately double their time resolution, and allow them to do
  direction finding and polarization studies.  They estimate that this would be
  a total increase of a factor of ~16 in their overall science return.  SWAVES
  does not have a way of modifying this additional telemetry rate--it's either
  all or nothing.

* SWAVES is the only instrument that wishes to stay on during the entire solar
  conjunction period.

* It was pointed out that after the spacecraft pass solar conjunction, some of
  the SEP instruments will no longer be aligned along the Parker spiral.  This
  will tend to mostly affect the initial data from an event.  After a few
  hours, the data become isotropic.

* NASA has put a page explaining the situation for the public at

				   Decisions

* For side lobe 1, it was decided that the spacecraft and instruments would
  change weekly, alternating between a mode where IMPACT gets more data, and
  mode where SWAVES gets more data.  In both modes, IMPACT should be able to
  include the additional 36 bps telemetry from the SEPT-NS measurements.  This
  alternating mode of operation will be evaluated after the first period of
  side lobe 1 operations, during ingress towards solar conjunction, to
  determine whether this should be used during the second period, during
  egress.

* For side lobe 2, it was decided that SECCHI should receive the extra 325 bps
  they requested for improved HI images.

* It was also decided that PLASTIC should receive some of their ApID 0x317
  telemetry, but that this should be reduced in volume within the combined
  IMPACT/PLASTIC IDPU.  The IMPACT and PLASTIC teams will get together and
  present a combined plan for making use of the additional 262 bps of residual
  telemetry


				 Action Items

* The IMPACT and PLASTIC teams will deliver to the SSC a combined plan for side
  lobe 2 operations by Tuesday, July 8.

* All the instrument teams will deliver to the MOC, with a copy to the SSC,
  their realtime telemetry requirements for side lobes 1 and 2 by Friday, July
  11.  These plans will include what ApIDs will be brought down, and what their
  rates will be.
