There’s no guessing about these. They aren’t anemic sunspecks that may or may not have been visible a couple of centuries ago. They are the real deal. Sunspot group 1026 on the lower left edge and newly formed group 1027 above the equator. While a couple of spots aren’t yet enough to end the solar drought we’ve seen, they are encouraging.
All of the spots are about the size of the Earth. You may recall that group 1026 was first, ahem, “spotted” by the stereo behind system which we covered last week on WUWT. The two groups have the potential to produce some solar flares. Group 1026 produced a few B-Class solar flares, 1027 has been quiet. Here’s the SWPC report defining both regions:

The 10.7 cm solar radio flux took a jump to 75 today, it may go higher as 1026/1027 continues to grow. It remains to be seen whether this is just a temporary energetic burst, with a lapse back to spotlessness, or if it heralds a new more active period of solar cycle 24.

Then there’s the slit experimint where waves counter each other making dark and light stripes.
Constructive and destructive wave behavior of light. It’s still taught in Astronomy courses as of 2 years ago, as well as the photon (particle behavior), bending of light by deep gravity wells, refraction and apparent decrease in velocity of light (c).

That was grand sport. What does the Most Reverend Anthony Watts drink? I will send him a bottle to put back in the deleted scenes, now that it is off of page one! >:-)
