I had not heard much about the Ivanpah Solar Power Facility for a while – no wonder – Recall we were told gas would be used to warm the boilers on cold Mohave Desert mornings. But when you convert the ever increasing natural gas usage to MWhrs – Ivanpah electricity production is mostly from natural gas.
I last posted on sunspots progression July last year –
SILSO report a string of 13 spotless days so far. As we grind on to a solar minimum around 2020.
From 2nd to 9th Jan so far and SILSO has New ‘Spotless days’ page with several graphics to ponder. OT – the SOI is nudging positive too.

Spotless days are listed at SILSO – it looks as though we just saw a run of 9 spotless days. My chart numbers come from NOAA’s SWO. The next minimum is a few years away yet. David Archibald has just posted at Anthony Watts.
Time to revist the progress of solar cycle 24 –
SIDC Brussels have produced a Version 2 series of sunspot numbers that looks very close to SWO NOAA.
SWO have a prediction out to end 2019 using the Version 1 RI numbers.
Does anybody know of any predictions for the timing of the next minima?
The ABC have this article claiming – Rooftop solar producing more energy than WA’s biggest turbine – Curtin University sustainability professor Peter Newman said – “It’s nearly 500 megawatts and it’s growing rapidly,..” Yet when I check NemWatch for WA I can only ever find a little over ~250MW for WA small solar. Is this because about half the output is used in the homes of the owners of these rooftop solar systems?
And of course the article seems to forget that these solar systems only work in the sunny hours – they make no electricity at night while the coal fired generators chug away 24/7. I wonder to what extent the WA grid can keep on accommodating increasing solar and wind power yet remain stable. I also wonder what is the cumulative cost of all the small scale solar subsidies paid out by the various Australian Governments.

Fascinating that the RAS promotes this research at a time the dominant climate change research paradigm is bleating on about global warming. Even the Fairfax media picks it up. Sun cycle’s cold facts say mini ice age on way
I note the abstract of their paper – Regional climate impacts of a possible future grand solar minimum – is misleading when it starts by saying – “Any reduction in global mean near-surface temperature due to a future decline in solar activity..” Stating that any decline is in the future. Yet in the paper they clearly state the decline is happening now and is accelerating. – “The decline in solar activity has continued, to the time of writing, and is faster than any other such decline in the 9,300 years covered by the cosmogenic isotope data1.” Never trust anything written by pro-IPCC sources without checking the fine print.
Two media reports – Solar decline may mean colder UK winters – Met Office study – and – Britain faces FREEZING winters as slump in solar activity threatens ‘little Ice Age’
RI numbers indicating sunspot activity could be off that shoulder –
