AR274 is approaching the Western limb and its size has not changed much.  AR2740 has widened a little and the light bridge is nicely visible in 540nm. Total Active Region Area for today is 170 millionths and the spot count is 4.  In addition, yesterday’s prom at the NW limb has rotated some more to the far side with the result that it is lower today as seen from Earth. For the rest, the Sun is quiet.
