The Solar Dynamics Observatory takes images of the Sun about every 10 seconds, so it easily was able to capture the Sun when the clocks and calendars lined up for a mathematically synchronous readout. Below is another image at the same time in different wavelength.
You can check out what the Sun looks like at anytime of the day or year the the
SDO website.
