In fact, this approaching Solar Maximum has
got professional aurora-chasing photographers like Antti Pietikainen in Finnish
Lapland very, very excited indeed, and with good reason when you look at the
image he captured way back in autumn 2011 (two years before Solar Maximum).
Antti said:
Last year’s autumn Draconoids meteor shower
peaked with full sky auroras. First two centimeters of snow, and I was at my
cabin in forest. I set the camera straight up against the aspen on the cabin
yard. I had a break from sauna and almost slipped at the porch when I saw the
sky on fire. I could stay out only a couple of minutes because I was barefoot
on the winter’s first snow.
If it was that good then, what will Solar
Maximum bring as this winter and next unfold, we wonder?
The winter of 2011/12 produced some
unforgettable auroras because of the increasing sunspot frequency and the power inverter of the solar flares, which cause coronal mass ejections or CMEs and subsequent
auroras. Remember all that talk about the northern lights being visible in Yorkshire and Northumberland and possible disruption to
our modern day way of life? That was all because the sun’s activity is growing
towards Solar Maximum.
The coming winters look to be just as good
if not better and while it’s lovely to see a low horizon aurora here in the
U.K., there is nothing to compare with standing on a frozen lake in the Arctic
and watching the lights swirl their hypnotic dance directly overhead.
We can’t wait, it is just too exciting!!!
Right now, there’s huge excitement among
those of us who hunt for the aurora borealis, also called the northern lights.
The lights are historically at their most frequent and spectacular when the sun
reaches the peak of its 11-year cycle of activity. This peak is known as Solar
Maximum,grid tie inverter and NASA is predicting it for the autumn of 2013.
NASA’s prediction is based in part on the
number of sunspots originating on our star’s surface and, as the name would
suggest, Solar Maximum is when the frequency of sunspots peaks. Here is how the
number of spot-less days has totted up over the last few winters:
Spotless Days
Current Stretch: 0 days
2012 total: 0 days (0%)
2011 total: 2 days (<1%)
2010 total: 51 days (14%)
2009 total: 260 days (71%)

Back in the winter of 2012/13, we found a
terribly useful page on NASA’s website, which provided sunspot frequency data
back to the turn of the Millennium. From the data, we created the graph below
showing that the next Solar Maximum would occur this winter.
We thought Solar Maximum might occur in
winter 2013. Now NASA says the maximum probably won’t come until late in 2013.

Since we extrapolated the data, things have
moved on, and NASA has revised its forecast. Initially, they suggested that
Solar Maximum would occur in May 2013, but very recently NASA revised that
prediction and now expect the maximum to occur in autumn 2013.
In the media, there was huge speculation
that this Solar Maximum would be the strongest for 50 years but NASA is now
predicting a weak maximum. In fact, it might be be the weakest maximum and
smallest sunspot cycle since 1906, according to solar panel physicists. Nevertheless,
the coming Solar Maximium means the northern lights will be at their best in
the winters of 2013 and 2014, and we’ve already seen many a stunning sky above
the auroral zone since the darker nights kicked in at the end of August 2012.
