FL360 is the bottom of [Other Center] Sector 45; FL350 and below is [Other Center] Sector 47. These 2 sectors are often combined. [Reporters Center] has control for descent from [Other Center]; but point out is required to [Other Center] Sector 47 if 45 and 47 are split. [Other Center] Sector 45 and 47 were split. OJT in progress at the D-side. Aircraft X at FL360 westbound in [Other Center] 45 airspace getting a bad ride; lower was better. Aircraft requested lower and R-side descended aircraft to FL340. No point out was made to [Other Center] 47. We were not aware of this event until 4 hours later. I do not recall what was happening at the time other than listening to the replay.I think we could use the draw function to note on the scope when 45 is open.
We have control for descent per the LOA with [Other Center]. I was currently training on the D side. [Other Center] 45 and 47 are usually combined but at this time they were not. [Other Center] Sector 47 is from SFC-350; [Other Center] Sector 45 is from 360-UNL. Aircraft X checked on at FL 360 and requested descent to FL340; due to bad rides. The R side did this without any prior pointout or coordination being done.We could write on the scope when 45 is open; especially when training.
Center Controller reported an airspace violation.
