Overall introduction of the anomaly and first data analysis from TDS and BIAS teams
Bias team data analysis
SOC first analysis	The three plots showed by Chris Watson Anomaly with respect to SC body rate in Y axis, just to illustrate position within a mosaic pattern and during, or close to, a slew Anomaly with respect to RPW parameter NIW00119 (current provided by a -5V rail in the bias unit?). Small downward change in the measured current following the anomaly, step probably smaller than the TM quantisation step so not very accurate. Illustration of similar (but short-lived) downward blips occurring during a WOL. Might be related, might be unrelated. Image Added Image Added Image Added
Conclusions & next steps	An ARB will be planned with SOC/MOC

Who?	What?	When?	Comment
Instrument risk mitigation and short-term operations
RPW sub-system Lead CoIs	Send to Xavier Bonnin the commands to mitigate the impact on-board (when know).	ASAP (at least before next ROB meeting on Feb 12)	For the moment only Bias team has identified a risk and will send commands.
Xavier Bonnin	Add into RPW Operations User manual to not plan Bias sweeps durint S/C attitude activities (slews)	ASAP

applied starting from the next IOR delivery (STP295)
Xavier Bonnin	Schedule a PA HF ON/OFF power cycle	TBD	Better if it is done after ARB meeting with MOC SOC must be informed when delivered IOR
Instrument anomaly investigation



Jan Soucek	Report to Xavier Bonnin any relevant information concerning TDS that can help to understand what on-board happened on November 13, 2023	ASAP
Xavier Bonnin	Write the anomaly report	TBD
Xavier Bonnin	See with Moustapha (and Antonio) which data are needed and how read them to analyse PA HF measurements

	ASAP
Milan Maksimovic	Plan a discussion with FIELDS team concerning dust impact (carbon fibers) in PSP	Can be planned during Joined RPW-FIELDS meeting at Orléans (last week of Feb. 2024)

after anomaly (Nov. 13, 2023 at 23:30z) Give information on the RPW Web portal at LESIA
