Future tohbans (beginning with this week's) should write corrections and updates directly in the manual, and inform A. Sterling of the changes. Jim Lemen has made a new version of the checksheet to correspond to the new manual. Changes to the checksheet should be marked on the checksheet and reported to A. Sterling. 8.5 Sirius Data Nothing to report. 8.6 Suggestion to DSN selection rule: mail from JPL I understand that you access RASM and choose the passes that are made available to you. We would like you to use the Wallops (WFF) passes as much as possible. In other words, if a pass from one of the DSN sites (Goldstone, Madrid or Canberra) can be substituted by a WFF pass, please use the WFF pass and delete the DSN pass, instead of vise versa. Please understand we are not asking you to give up any coverage but if the same coverage can be accomplished by using WFF instead of the DSN, we would like you to do so. (Albert Chang) 8.7 New Email address for DSN cancellations : part of mail from Arthur E Andujo .... could you change the address you use to send the weekly deletes for SOLAR-A, FROM: dsnsched@dsn.jpl.nasa.gov dsnsched@lilypad.jpl.nasa.gov AND BEGIN USING: DSNSched@jpl.nasa.gov ^^^^^^^^^^^^^^^^^^^^^ This would facilitate a quicker and more efficient delivery of messages. 8.8 DSN schedule delivery DSN schedules delivery software did not work right W28, and we got almost all the schedules via RASM. Please check DSN schedules via RASM. 9. Action Items None. End of Report
