Event horizon telescope has been taking data of the Sag A* black hole but the data is still being processed and yet to be released.
Is this due to occlusion?
A lot of the problems with imaging the black hole at the center of the milkway is that we would have to look along the midplane of the galaxy towards the center. That is where a lot of gas and dust is to be found and the radio waves interact with that stuff. They did take data and are working on it, but the image of M87* was easier to reconstruct and went out first.
