What causes this on my negatives?

Are these light leaks?

This was my first roll with my new Ondu 6x6 pinhole.

Acros 100 processed the way I usually do:
HC-110 dilution E, 8 min @ 20°, total 600ml fluid in a Paterson tank With a rubber band around the post to help the reel in place.)

I'm wondering if light somehow leaked in the two days the roll was sitting on my counter after it was exposed.

I appreciate your help!

Light leaks or improperly wound or handled 120 roll film.

Yeah, I'd say light leak.

It seems your roll wasn't properly held tight after being exposed, perhaps the taping was loose or it loosened up when you removed it from the camera? Just speculating.

It's a like leak, but the pattern makes me wonder if it isn't camera related? Of course if it was lying in the horizontal position, with a strong light above, then it could be from a bow in the exposed roll. The tern "new camera" makes me a little more than just suspicious in this case.

Yes, light leak, film maybe not rolled tightly enough.

Because it's not in exactly the same spot on each frame, I'd say it's more likely that the roll wasn't tight enough rather than the camera. When the roll is done and you remove it from the camera, it doesn't always stay rolled tightly (some cameras don't make it tight to begin with). If it's loose at all, the light gets in easily. It doesn't take much. Yup, BTDT.

I got something almost identical when a film wound too loosely onto the take up spool and I removed it under bright sun.

Thanks for all the replies. Upon closer examination, the leak marks are worse towards the end of the roll, so I'm pretty sure it's a spooling issue. I'll try another roll and advance the film more carefully, load and unload in subdued light, tape the roll carefully, and keep the exposed roll in darkness until I process it. (All best practices I should've done anyway!)

It's a light leak from the film not being wound up tight enough. Same thing can happen with my Holga if I'm not careful.

I guess your pinhole is not keeping the film flat during expose.
