This segment covers the period from 1 December 2023 to 5 April 2024, part of the Dayside 2024 season.

Baseline telemetry is 140%.

The period includes most of the season of ‘Short Eclipses’ in February - May 2024 when all instruments will be switched off.

The ESOC's dates for the payload to be off during the Short Eclipse season are:

* C2 01/02/2024 04:00 - 24/05/2024 04:00
* C1 19/02/2024 20:00 - 03/05/2024 14:00
* C34 26/02/2024 18:00 - 06/04/2024 14:00

There will be re-entry manoeuvres on SC2 on 15/01/2024, 16/01/2024, 24/01/2024, 25/01/2025 and on 01/02/2024, 02/02/2024 (February's manoeuvres are back-up). The full timetable is available here ​http://jsocwiki.rl.ac.uk/attachment/wiki/WikiStart/manoeuvres_nov2023_feb2024_SC2.pdf. These manoeuvres have an increased margins and all instruments will be switched off for the whole duration of the manoeuvres.

Cluster crosses the predicted magnetopause from: SC1 - 07/11/2023, SC2 - 10/11/2023, C34 - 14/11/2023. 

Cluster crosses the predicted bow shock from: SC1 - 16/12/2023, SC2 - 18/12/2023, SC34 - 25/12/2024.

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 southern hemisphere. 

This segment contains the PP1210 which covers most of the eclipse season and is developed to be used for a 'generic OBRQ' later in the mission when paylad on SC134 (CIS, FGM, PEACE, WEC) is swicthed ON for a short amount of time into NM1-BM1-NM1 telemetry sequence for a specific science target.

** Science planning around the time of the start of the Short eclipse season on SC2 was updated on 10/10/2023 to accommodate the ESOC's request to switch off payload on SC2 for the eclipse season on 01/02/2023. Updated orbits 3737 and 3738, tables with *v2* reflects the introduced changes. 

** On 16/10/2023 the MSP50.1 by_orbit table was updated for orbit 3714, as one BM1 mode interval was missing in that table.

** On 16/11/2023 the MSP50.1 science planning was updated (from orbit 3745) to accommodate the ESOC's schedule for the Short Eclipse season 2024 and for the special operations in PP1210 (development of generic OBRQ). Tables MSP50p1_byorbit_draft_v4.pdf and MSP50p1-4SC_BM1_draft_v3.pdf reflect the changes. 

** On 05/12/2023 table by_orbit has been updated for the Southern AAR entry in orbits 3738-3739, as a wrong mode was shown. Table in MSP50p1_byorbit_draft_v5.pdf shows the correct, BM2, mode. All other tables were correct, as well as MSP_ASCII.lst.
