ANNOUNCEMENTS
-------------

* None

INSTRUMENT and SPACECRAFT STATUS
--------------------------------

* Ahead is operating nominally.  PLASTIC is in operational mode,
  but with a moderately higher than normal background rate.

* Four years after the initial loss of communications anomaly with
  the Behind observatory, NASA has directed to cease periodic
  recovery operations with the last support on October 17, 2018.


DISCUSSION AND OPERATIONS CONSTRAINTS
-------------------------------------

Week 2 (Jan 5-11)

* No ground system anomalies this week!

* The average daily science data return for Ahead was 7.0 Gbits during this
  week.

Week 3 (Jan 12-18)

* Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage
  is nominal.

Week 4 (Jan 19-25)

* Ahead has fourteen passes during the week, all at 720 kbps, and overall coverage
  is nominal.

Week 5 (Jan 26 - Feb 1)

* Ahead has fifteen passes during the week, all at 720 kbps, and overall coverage
  is nominal.

Week 6 (Feb 2-8)

* Ahead has fifteen passes during the week, all at 720 kbps, and overall coverage
  is nominal.

* The 78th SECCHI stepped calibration roll is scheduled for Monday, February 2nd,
  at 07:35 UT.

* The Artemis II launch opportunity window opens at the end of week 6.  There may
  be schedule adjustments for weeks 6-8 in the near future.

Week 7 (Feb 9-15)

* Ahead has sixteen passes during the week, all at 720 kbps, and overall coverage
  is nominal.

* The 183rd momentum dump is scheduled for Wednesday, February 11th, at 17:45 UT.

* The 25th Solar Orbiter remote sensing window begins Thursday, February 12th. 

Week 8 (Feb 16-22)

* Ahead has fifteen passes during the week, fourteen at 720 kbps, and one ESA support
  at 480 kbps.  Overall coverage is nominal.

* On Tuesday, February 17th, an ESA New Norcia track is scheduled from 18:05 to
  18:55 UT.  This track will be at 480 kbps, and it is planned to use this rate for
  all ESA support tracks going forward.  Owen will monitor the distrubution of DSN
  and ESA tracks to ensure that all data continues to be collected with the new,
  lower ESA downlink rate.
