What does this light sequence mean?

[PhantomPilotGuy]

I am getting the following light sequence after 15 no problem flights.

2 long red light flashes followed by 4 short green flashes. It has happened every flight since.

Full satellite count.

Did IMU recal successfully. Flying in the same location I have since I bought it.

Does anyone know what it means?
