Mercury's transit across the sun

[BobDavid]

I set my camera up and ate lunch as Mercury was in the process of making its transit across the sun. I am guessing that the object above the northern half of the frame is either a satellite or a sun spot. Mercury is the tiny dot below the yellow line

Fascinating.

But I think the upper dark spot is a drone belonging to another photographer who was trying to get too close to the sun.

Excellent explanation…

Nice work. Do you use a solar filter? I made one for the 2012 Venus transit. I tried to get foreground and the sun/planet combo and it technically worked but could use some refinement. I would have liked to try again today but couldn't pull it off.

It is a sunspot. I wasn't sure until after I posted.
