Solar Cycle 24 has allegedly arrived.

It been said before but according to the Solar Influences Data analysis Center (SIDC) at the Royal Observatory of
Belgium, Solar Cycle 24 has arrived.
Space weather dot com clickerty you cursor here reports
SOLAR CYCLE 24 BEGINS:
Solar physicists have been waiting for the appearance of
a reversed-polarity sunspot to signal the start of the next solar cycle. The
wait is over a magnetically reversed sunspot emerged at solar latitude 30 N yesterday.
This marks the beginning of Solar Cycle 24 and the first step toward a new solar
maximum. Intense solar activity won't begin right away. Solar cycles usually
take a few years to build from solar minimum.
Solar Max is expected in 2011 or 2012, so it's a slow journey, but we're on our way!

Maybe they should spend more time on the relative dead bands than predicting cycle climaxes lmao.
But I have read somewhere that some backwards sun spot cycles often ear mark the end o the solar minimum and the start of the new cycle.
I think there should be a dramtic improvement by the end of this year with some occasional good solar storms in this year.
This is not a Psychic Prediction by the way lmao

Dec. 14, 2007: The solar physics community is abuzz this week. No, there haven't been any great eruptions or solar storms. The source of the excitement is a modest knot of magnetism that popped over the sun's eastern limb on Dec. 11th, pictured below in a pair of images from the orbiting Solar and Heliospheric Observatory (SOHO).
It may not look like much, but "this patch of magnetism could be a sign of the next solar cycle," says solar physicist David Hathaway of the Marshall Space Flight Center.
Above: From SOHO, a UV-wavelength image of the sun and a map showing positive (white) and negative (black) magnetic polarities. The new high-latitude active region is magnetically reversed, marking it as a harbinger of a new solar cycle.
For more than a year, the sun has been experiencing a lull in activity, marking the end of Solar Cycle 23, which peaked with many furious storms in 2000--2003. "Solar minimum is upon us," he says.
The big question now is, when will the next solar cycle begin?
It could be starting now.
"New solar cycles always begin with a high-latitude, reversed polarity sunspot," explains Hathaway. "Reversed polarity " means a sunspot with opposite magnetic polarity compared to sunspots from the previous solar cycle. "High-latitude" refers to the sun's grid of latitude and longitude. Old cycle spots congregate near the sun's equator. New cycle spots appear higher, around 25 or 30 degrees latitude.
The region that appeared on Dec. 11th fits both these criteria. It is high latitude (24 degrees N) and magnetically reversed. Just one problem: There is no sunspot. So far the region is just a bright knot of magnetic fields. If, however, these fields coalesce into a dark sunspot, scientists are ready to announce that Solar Cycle 24 has officially begun.
Below: Solar Cycle 23 is coming to an end. What's next? Image credit: NOAA/Space Weather Prediction Center.
Many forecasters believe Solar Cycle 24 will be big and intense. Peaking in 2011 or 2012, the cycle to come could have significant impacts on telecommunications, air traffic, power grids and GPS systems. (And don't forget the Northern Lights!) In this age of satellites and cell phones, the next solar cycle could make itself felt as never before.
The furious storms won't start right away, however. Solar cycles usually take a few years to build to a frenzy and Cycle 24 will be no exception. "We still have some quiet times ahead," says Hathaway.
Meanwhile, all eyes are on a promising little active region. Will it become the first sunspot of a new solar cycle? Stay tuned for updates from Science@NASA.

Nice graphs they made and all that, still does not explain the hiss and quiet that there these days 
But saying that, 1w on a handheld with a homemade antenna made it to the UK

Best I have managed so far is 1.5 watts on the VX-7R during a 2 meter opening. We think it was a French repeater as it was on a very weird frequency (145.3??) & the other guy was in Hamburg & also on a handy.
I have had a couple of good homebase 6 meter QSO's using 0.5 to 2.5 watts, but I'll not count them.

Great Indeed Daxi, those VX7r are indeed working well. If only it had the 6.25 then all would be even more better
