Venus Transit Testing
Today at 1800 UT (2 pm ET) the AIA instrument started testing the instrument modes they will be using during the Venus transit on June 5-6. AIA images will be unavailable until the testing is complete (about 30 minutes). Some of the partial and striped images may be visible. There is nothing wrong with AIA and we will return to our normally scheduled pictures as soon as the testing is finished.
