This segment covers the period from 14 May 2023 to 30 June 2023.

Baseline telemetry is 140%.

There will be no moon eclipses in this segment.

There will be no manoeuvres during this segment.

Cluster crosses the predicted bow shock until: C34 - 17/05/2023, C1 - 24/05/2023, C2 - 28/05/2023

Cluster crosses the predicted magnetopause until: C34 - 24/06/2023, C1 - 29/06/2023, C2 - 03/07/2023

The main science targets are conjunctions between Cluster and MMS and/or THEMIS at the magnetopause, bow shock and inside the magnetosheath, and auroral acceleration region in the northern hemisphere. One hour of BM1 per month is also allocated to PEACE/WHISPER cross-calibration intervals.

Science planning for one northern AAR interval was adjusted on 13/03/2023, affected orbit is 3627, single SC-ops BM2 on SC12 was allocated for 45 mins. This updated is reflected in tables MSP49p1_byorbit_draft_v2.pdf and MSP49p1_singleSC_Bm2_v1.pdf.

A mistake in the table for 4SC BM2 mode allocation was corrected on 03/04/2023 - BM2 mode for the events on 14 and 23 May were allocated on all 4 spacecraft, not on SC134. Table with *V2* reflects the right allocation.
