The Sun has likely already entered into a new unpredicted long-term phase of its evolution as a hydrogen-burning main sequence star — one characterized by magnetic sputtering indicative of a more quiescent middle-age. Or so say the authors of a new paper submitted to The Astrophysical Journal Letters.
Using observations of other sunlike stars made by NASA ’s Kepler Space Telescope, the team found that the Sun is currently in a special phase of its magnetic evolution.

Heretofore, the Sun was thought to have been just a more slowly rotating version of a normal yellow dwarf (G-spectral type) star. These results offer the first real confirmation that the Sun is in the process of crossing into its magnetic middle age, where its 11-year Sunspot cycles are likely to slowly disappear entirely. That is, from here on out, the Sun is likely to have fewer sunspots than during the first half of its estimated 10 billion year life as a hydrogen-burning star.
“The Sun’s 11-year sunspot cycle is likely to disappear entirely, not just get less pronounced; [since] other stars with similar rotation rates show no sunspot cycles,” Travis Metcalfe, the paper’s lead author and an astronomer at the Space Science Institute in Boulder, Colo., told me.[…]
Another two hour broadcast of rock n roll music–“The Classics Experience”–will happen tonight via the transmitters of Shortwave Service in Kall, Germany.
6005 kHz Friday June 24th 1800-2000
3985 kHz Saturday June 25th 0000-0200
Both broadcasts will have the MFSK32 text and picture as well. However, the picture will NOT decode properly and it isn’t a problem on your end. All it is is a rebroadcast of the WINB/WRMI, complete with WRMI/WINB mentions and no mentions of 3985/6005 kHz.
By the way, you can also expect my show on Laser Hot Hits in the 49 meter and 75 meter band sometime next month, airing on nearly a daily basis for a month or so.

Babcock has tests today, June 14, at 2130-2145, to Antarctica on 5985 (Woofferton), 6035 (Dhabayya), 7360 (Ascension), and 9720 (Woofferton).
I think we can assume three of these frequencies will be used for the annual mid-winter transmission to Antarctica on June 21 at 2130-2200.
I will attempt to receive the tests broadcasts today here in Québec; it will give me an indication if I stand a chance of reception next week.
I would appreciate any recordings of the test broadcast to add to the Shortwave Radio Audio Archive.
As Dan mentions above, next week, Tuesday, June 21, the BBC Antarctic Midwinter broadcast will take place once again. This is one of my favorite shortwave events of the year. Like last year, I hope we receive recordings of the on air event from across the globe!
We’ve just posted yet another excellent recording by Tom Laskowski to the Shortwave Radio Audio Archive. I thought a number of Post readers might appreciate this one.
KNLS – Anchor Point, Alaska, from what I believe is a test transmission on August 1, 1983. According to Wikipedia, KNLS signed on the air July 23, 1983. The program consists of the sign-on ID in English and Russian then is mostly a mix of Big Band music. This recording is 31 minutes long.
Tom’s receiver was a Sony ICF-2001 and he started recording at 09:00 UTC on 11.820 MHz. His location, at the time, was South Bend, Indiana (USA).
