From: Al Frandsen Subject: ACE Status for the Week Ending November 14, 1997 >From: Don Margolies >Subject: ACE Status for the Week Ending November 14, 1997 > >Hello All, > >Operations this week went fairly well. An anomaly regarding CRIS occurred >on Wednesday, November 12. During a commanding exercise, CRIS stopped >transmitting science data and stopped accepting commands. The instrument >team and the FOT decided to turn CRIS off and power cycle it. When the >instrument came back up it operated properly. The unit was reconfigured, >checked out and an anomaly report was generated. The analysis of this event >is ongoing but the current thinking is that it was the result of a software >glitch. > >As of now the observatory and all instruments are working as planned. All >of the instruments have had their high voltages raised to operational >levels. Even SWICS and SWIMS are -almost- there. Peter Bedini, UMD, is >being very cautious and just tweaking the voltage levels up a little bit >more at a time. > >For those of you who haven't seen the data on the ASC home page I want to >point out two interesting items. The first was a quick release of SEPICA >data taken on September 18-20. During this time the SEPICA high voltage was >only at 3000 volts (vs the 24,000 volts today) but from this data the >instrument collected more iron ions than were integrated over all 3He-rich >events during the entire ISEE-3 mission with SEPICA's predecessor. The >second item concerned the two large solar energetic particle events of >November 4 and 6. In reviewing only twenty percent of the data that will be >available to SIS from this event, the SIS team has determined that the data >already exceeds the world's supply of high- resolution isotope measurements >in large solar particle events. > >Carline Cazeau, the lead of the ACE Flight Ops Team, received an award from >the National Technical Association as one of the NTA's 1997 Top Women in >Science and Engineering. The presentation was made at the NTA's 69th Annual >Conference in Philadelphia last week. Since GSFC is one of the sponsors of >the event, Center Director Joe Rothenberg attended the award ceremony. > >The Science Team will have its next meeting at the GSFC on November 24 and >25. On the 24th the meeting will be in Building 26, Room 205. Starting time >is 0830 hours. > >Don >
