Hi Tony
That is known as the "0° to 180° meridian arrow"
You will note that it also has a thin line through it which starts from the pole at the center and runs to the edge. With any transparent overlay in place, you will note that the fat arrow and the corresponding thin line are perfectly aligned with your meridian.
This is used to set LHA Aries.

Dear Brad,
The "fat" black arrow I'm asking about is in the red oval here.
Thank you in advance.
Warm regards,
