When the sheet is produced you sometimes get material or air trapped inside the ingot as it cools. The metal crystallises at the inner surface of the inclusion. As it is rolled progressively thinner these inclusions can become exposed. What you have there is a couple of flaws arising from the trapped air. Attached is an example where you can see the inclusion and crystallised metal to good effect.
