We apologize for the lack of new images from AIA. This is due to issues outwith our control. We create the images you see from AIA level 1.5 data products (the number refers to the degree of image calibration, etc., that has been applied to the raw data) that are processed at SDO Joint Science Operations Center. As you can see, those data appear to be lagging at the moment. As soon as the data returns, Helioviewer will automatically generate images and make them available.
