This page is only intended to give some context information on the evolution of the active region followed during the Solar Orbiter Observing Plan (SOOP) and not precise pointings.
The following information is given by inverse chronological order: top is the most recent data, bottom oldest.
Update 28 October - 2 November 2022: new sets of active regions (w/ sunspots), in relation with several SOOPs
Since October 27th, new groups of sunspots have appeared on the solar disk, which have been the (renewed) target of the 'Long-term Active Region' SOOP as well as 'Active region heating' and 'Atmospheric Dynamics Structure' SOOPs. These new groups of sunspots are: NOAA AR13131, AR13133 and AR13135.
A view from the HMI Continuum (https://solarmonitor.org/) is given below:
These groups of sunspots are relatively active, as can be seen with this multiview of Solar Dynamics Observatory AIA and HMI videos covering 28th October - 2nd November:
20221102-Overview-1028-1102.mp4
Until the end of the SOOPs (6th November), the targets will focus on these active regions and sunspots, as per the detailed pointing table (https://issues.cosmos.esa.int/solarorbiterwiki/x/DqWVBg).
27 October 2022: target past central meridien + new group of sunspots nicely evolving
The first target is now western side of the central meridian. Tiny sunspots have been seen to appear in the continuum, however the region as a whole still appears to be dispersed.
The new group of sunspots with a strong leading polarity is nicely evolving, with a filament eruption seen back on the 26th and a lot of coronal loop activity.
26 October 2022: target at central meridian as seen from Earth + new group of sunspots
The target is now right at central meridian as seen from Earth. The region continues to evolve, with a magnetic field dispersion, open field lines and closed field lines system.
A new active region is now appearing on the eastern limb, with strong magnetic field concentrations with well defined sunspots. These new sunspots will be the target of observations on October 29th.
25 October 2022: target approaching central meridian as seen from Earth
As of 25th October, the target is still seen on disk and is approaching the central meridian as seen from Earth.
No major activity but the coronal loops are still brightened, with dynamics on the west side of the target where the open field lines are.

24 October 2022: target continues its evolution on disk
Target continues to evolve on disk - magnetic field is very disperse with no sunspot.
Some activity seen in the coronal loops. Interesting region with open field lines on the west of the target.
23 October 2022: target continues its evolution on disk
Several images from SDO/HMI and AIA in different passbands: the region of interest continues its evolution on disk.
No sunspot associated to the region which has a disperse magnetic field, but a few coronal activity with some coronal loops brightening here and there.
22 October 2022: target continues its evolution on disk - filament and open fields
The target is still sustained as of 22 October. The region moves slightly westward of the solar meridian as seen from Solar Orbiter (top row).
The region shows the presence of filaments and still has the network of open field lines on its west side.
Bottom row shows different views from SDO/AIA and HMI.
21 October 2022: target moves from limb to on disk as seen from Earth
The target is now at the center of the solar disk as seen from Solar Orbiter.
There are no strong magnetic fields associated to it so far as seen from Earth (continuum data doesn't show any sunspot), however some coronal activity has been seen in the different SDO/AIA passbands.
20 October 2022: target moves from limb to on disk as seen from Earth

19 October 2022: target starts to appear on the limb as seen from Earth - SDO shows loops
The system of loops (pink square) on the western side of the target as seen from Solar Orbiter (EUI/FSI) seems to start showing on the eastern limb (as seen from Earth). SDO/AIA captures some dynamics of these loops.
Observations at different ground-based observatories are now starting!
Two little videos showing some corona loop dynamics as seen by SDO/AIA.

IRIS also saw the system of loops and the edge of the active region during its coordinated observations:
18 October 2022: continuous evolution, AR
17 October 2022: continuous evolution
The active region is still situated on the solar eastern side of the central meridian.
It shows a little complexity, with potentially connection with the surrounding
16 October 2022: Beginning of the observations for Solar Orbiter
16th October marks the beginning of the campaign for Solar Orbiter.
The Active Region is ideally placed, on the solar eastern side of the central meridian, meaning that it is optimally placed to allow a long-term follow-up with the remote-sensing telescopes on board the mission.
The Sun is collaborating!

FSI images used for the pointing decision for the 19 October Solar Orbiter observations.
The position of (previously known as) AR 13110 on the North East is ideal for a monitoring start on 16 October.
A nice prominence eruption is seen around 16:30UTC, meaning that the region is quite active.

30 September 2022 - 02 October 2022: Target as seen from Earth
Between 30 September and 2 October, active region 13110 was split into 13110 and 13113. This is the region of interest that is currently planned to be followed by Solar Orbiter.
