This video compresses about an hour of solar activity around a sunspot to a little over ten seconds.
Via APOD:
The Sun’s surface keeps changing. The above movie shows how the Sun’s surface oozes during a single hour. The Sun’s photosphere has thousands of bumps called granules and usually a few dark depressions called sunspots.
Always interesting to see this.
BTW….10 Meters is wide-open again. I heard a guy in French Polynesia talking to a guy in England! Both sides were Q5, so I must be in the middle of one of their hops.
Ten meters is a very interesting band. When I lived in Venice, CA, I worked a guy in Venice, FL. We chewed the rag for a while and then he reported that my signal took a fade. Funny, I thought, He’s 40 over S9. Looking at the rig, I then noticed that the drive was turned all the way down. I turned it up and he asked if I turned on the linear. In reality, I had been yakking with him running 400 milliwatts.
I do miss some of it, that’s for sure. Maybe one of these days . . .
Yeah, 6 is that way, too. When the band is open, a *little* bit of power goes a long way!
When I was in the apartment in Torrance I couldn’t run more than about 50 Watts on 6, or I’d make the door bell for the downstairs business go nuts. We had a BIG opening one day, and even with 50 Watts to a half-wavelength vertical, people said I was 40+ over S9.
Two weeks ago on 10 I worked South Korea, Taiwan, and mainland China on 10 using SSTV!
