Latest news

The delivery of new RPW L1 and L2 CDF files to the Solar Orbiter Archive (SOAR) at ESAC has been achieved, except for few files [1]. See Data releases notes section below for details about the main changes brougth to the CDF files.
The nominal delivery of RPW L1 and L2 data will be progressively resumed in the next weeks.

The delivery of new RPW L3 CDF files to the SOAR will be scheduled later in the year.

Daily availability of all in-situ instruments can be found here.
Main on-board activitities related to RPW are reported in the operations calendar.

Known issues with RPW data

• On November 13, 2023 around 23:36z, RPW temporarily lost its capability to measure signals with the antenna 3 (MY). This problem persisted until Feb 27 at 22:40z when the signal was recovered again. After this date, the ANT3 signal was temporarily lost on a few more occasions until mid-March 2024. No new failure has been reported since. This issue had affected some of the RPW science data acquired during this period. Please read CAVEATS and QUALITY_FLAG in CDF or contact the person in charge for more details.

• Issue raised concerning the solo_L1_rpw-hfr-surv and solo_L2_rpw-hfr-surv data time stamping. The Epoch times of the data sample is expected to increase monotonically, which is not always the case. Investigations are in progress. A new set of HFR L1/L2 CDF files will be released as soon as the root cause will be identified and the problem fixed.

• Issue raised concerning the solo_L2_rpw-tnr-surv data: the cross-correlation is not normalized as expected in the CDF files. A patch is in preparation. New CDF files will be published after correction.

• EM contaminations identified by the RPW Team in science data are listed here.

Information about releases notes can be read in the global attribute MODS in the CDF files.

List of major data reprocessing

A major update of the RPW L1 and L2 CDF files have been performed on June 2025.
Main changes are:

• Use CDF 3.9 (instead of 3.7 previously)
• CDF GZIP.6 compression applied on all zVariables excepted Epoch
• CDF files are now fully compliant with Solar Orbiter metadata standards 2.6 (https://s2e2.cosmos.esa.int/confluence/display/SOSP/Metadata+Definition+for+Solar+Orbiter+Science+Data)
• Fix minor remaining inconsistencies in the CDF metadata
• Update content of few data products (see MODS global attributes in the CDF files for details.)

NOTE: Update of the RPW L3 CDF files is in preparation.
