Notes
Item 1
No posterior support for NSBH origin
Item 2
HLV event with very good localization
Item 3
Low-mass BBH with positive chi_eff
Item 4
Preferred pipeline pycbc gave p_NSBH around 0.14, so it is HIGH_PROFILE

Notes
Item 1
Automatic online PE run succeeded
Item 2
When this file is updated add the contents as a comment on the relevant git issue.
Item 3
Perform a review of the online result and assess if it is sufficent for sending a skymap.
Item 4
Instructions can be found [here](https://git.ligo.org/pe/O4/o4b-rota/-/wikis/Review-instructions).
Item 5
Results copied from /home/pe.o4/O4b/S240915b/online/bilby
Item 6
Low-mass BBH, with very good localization
Item 7
The issue was resolved initially with a blank sky volume plot, later fixed by Deep Chatterjee
Item 8
The online run looked good and was used to update the skymap and release the GCN updates
Item 9
The tight localization resulted in a failure of the sky volume plotting, which blocked the release of the GCN alert update
