some scattered medium size sunspots appeared in the midle sector of the eastern limb, not what expected indeed; on the other hand, AR3738 continues to extend, now it is 12 Earths wide and the western core has grown big enough so as to be observable with protected eye alone; the closeness of this spot to the sun equator is striking even more
considering the 4° shift of the latitude grid to the south
