The largest and Darkest Sunspot on the solar disk. is AR 4536

Rain is on the way for the High Desert, and for now the sky is full of thin clouds and haze. But through that, we still see the largest and darkest sunspot on the solar disk. AR 4536. It is seen following departing sunspot groups, 4537, 4538 and 4534. There are several other sunspots on the Sun today, but they are difficult to see through the haze. And all of them have stable magnetic fields that pose no threat for strong flares.
