They’re not microlenses sadly
Microlensing, or m-i lensing, is a gravitational effect that occurs when a massive object bends light from a background object, creating distorted, magnified, or brightened images of the background object. This effect is most extreme around massive objects like black holes and galaxies, but even stars and planets can cause detectable microlensing.
Aty first I thought you’re were saying microlensing, but you’d mean multiple images?

m-i ~ hence the circles ~ could be l-o-s also
