Sunspot Count Falls to Zero… Then Skyrockets to 90.

Solar Dynamics Observatory image showing Sunspots just before 0400 on 7/16/11.

On 7/15/2011 @ 0226 the Sunspot count stood at 90.

At 0321 on 7/15/2011 it had dropped to 79.

That number held through 0216 on 7-16-2011.

The image above is the most recent observation posted on the SDO site. By my count the Sunspot number is between 10 and 12.

At 0432 on 7/16/2011, the Sunspot count stands at zero (0).

How long will zero be the number? A few hours? A day? We’ve seen one spotless day in 2011. This could be the second.

We shall see in a few hours!!

—–UPDATE @ 1410 7/16/2011—-

Sunspot number rockets to 90 @ 1410, up from 79 @ 0216 7/16/2011.

So was the blank just a mirage? I doubt it. The difficulty lies in real time sunspot numbers and real time observations. The international sunspot number was 70 when the Boulder, CO number was 79.

Here is the drawing-

But there is no update as of posting?!! +24hrs without a new image?


I would like to know why there is no new images. And how can you get 90 sunspots out of this image-
