Parker Solar Probe Prepares for New Science, New Records on Fourth Solar Orbit – Parker Solar Probe

The fourth pass of the Sun by Parker will be on the 29th January. It’ll be only 11.6 million miles from the Sun, a new record (the first three passes were at 15 million miles away).

Should You Wait for Perovskite Solar Cells?

Should You Wait for Perovskite Solar Cells?

Research into more efficient methods of generating solar electricity is ongoing. Besides universities and industrial concerns, even the federal government is involved, conducting solar energy research at the Solar Energy Research Facility in Golden, Colorado. Solar scientists within all of these organizations are studying the application of perovskites in photovoltaic cells. So should homeowners…

Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale

Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale

As many of you know we will have Valentina on our Youtube channel to discuss this paper!

The article has been accepted and can be found on Nature.com Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale

The Quick result for those not keen to the science, is that the next Modern grand minimum of solar activity is upon us in 2020–2055.

This paper also shows the AGW alarmist out there how warming is NATURAL!!! 

Top plot: the close-up view of the oscillations of the baseline magnetic field (dark blue curve) in the current and past millennia with a minimum occurring during Maunder Minimum (MM). The irradiance curve (magenta line) presented from Krivova and Solanki27,28 overplotted on the summary curve of magnetic field (light blue curve)6. Note the irradiance curve is slightly reduced in magnitude in the years 0–1400 to avoid messy curves. The dark rectangle indicates the position of MM coinciding with the minimum of the current baseline curve and the minimum of the solar irradiance27,28. The scale of the baseline variations are shown on the left hand side of Y axis, the scale of the summary curve – on the right hand side. Bottom plot: variations of the Earth temperature for the past 140 years derived by Akasofu26 with the solid dark line showing the baseline increase of the temperature, blue and red areas show natural oscillations of this temperature caused by combined terrestrial causes and solar activity. The increase of terrestrial temperature is defined by 0.5 °C per 100 years26.

We are excited to break down the new findings for everyone!  I am guessing either this week or next week since we both have quite a lot going on.

Here is the ABSTRACT:

Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a Modern grand minimum similar to Maunder one. On the other hand, a reconstruction of solar total irradiance suggests that since the Maunder minimum there is an increase in the cycle-averaged total solar irradiance (TSI) by a value of about 1–1.5 Wm−2 closely correlated with an increase of the baseline (average) terrestrial temperature. In order to understand these two opposite trends, we calculated the double dynamo summary curve of magnetic field variations backward one hundred thousand years allowing us to confirm strong oscillations of solar activity in regular (11 year) and recently reported grand (350–400 year) solar cycles caused by actions of the double solar dynamo. In addition, oscillations of the baseline (zero-line) of magnetic field with a period of 1950 ± 95 years (a super-grand cycle) are discovered by applying a running averaging filter to suppress large-scale oscillations of 11 year cycles. Latest minimum of the baseline oscillations is found to coincide with the grand solar minimum (the Maunder minimum) occurred before the current super-grand cycle start. Since then the baseline magnitude became slowly increasing towards its maximum at 2600 to be followed by its decrease and minimum at ~3700. These oscillations of the baseline solar magnetic field are found associated with a long-term solar inertial motion about the barycenter of the solar system and closely linked to an increase of solar irradiance and terrestrial temperature in the past two centuries. This trend is anticipated to continue in the next six centuries that can lead to a further natural increase of the terrestrial temperature by more than 2.5 °C by 2600.

NOAA & NASA Solar Cycle 25 Forecasts - A Comparison

NOAA & NASA Solar Cycle 25 Forecasts - A Comparison

[embedyt] https://www.youtube.com/watch?v=jP9_4uoEdKg[/embedyt]

The new research was led by Irina Kitiashvili, a researcher with the Bay Area Environmental Research Institute at NASA’s Ames Research Center, in California’s Silicon Valley.   It combined observations from two NASA space missions – the Solar and Heliospheric Observatory and the Solar Dynamics Observatory – with data collected since 1976 from the ground-based National Solar Observatory.

One challenge for researchers working to predict the Sun’s activities is that scientists don’t yet completely understand the inner workings of our star. Plus, some factors that play out deep inside the Sun cannot be measured directly. They have to be estimated from measurements of related phenomena on the solar surface, like sunspots.

Kitiashvili’s method differs from other prediction tools in terms of the raw material for its forecast. Previously, researchers used the number of sunspots to represent indirectly the activity of the solar magnetic field. The new approach takes advantage of direct observations of magnetic fields emerging on the surface of the Sun – data which has only existed for the last four solar cycles.

Mathematically combining the data from the three sources of Sun observations with the estimates of its interior activity generated a forecast designed to be more reliable than using any of those sources alone.

In 2008 the researchers used this method to make their prediction, which was then put to the test as the current solar cycle unfolded over the last decade. It has performed well, with the forecast strength and timing of the solar maximum aligning closely with reality.

Her results are as follows:

Using the currently available observational data, predictions and prediction uncertainties have been calculated for Solar Cycle 25.   The results, based on both the sunspot number series and observed magnetic fields, indicate that the upcoming Solar Maximum (Solar Cycle 25) is expected to be significantly weaker than that of the current cycle (which near its end). The model results show that a deep extended solar activity minimum is expected in about 2019-2021, the maximum will occur in 2024 – 2025, and the sunspot number at the maximum will be about 50 (for the v2.0 sunspot number series) with an error estimate of ~15-30%. The maximum will likely have a double peak or show extended high activity over 2 – 2.5-years.

  NOAA Has also released a more modest preliminary forecast for Solar Cycle 25 on April 5, 2019. Similar to Kitiashvili’s predictions they state Cycle 25 will be similar in size to cycle 24.  It is expected that sunspot maximum will occur no earlier than the year 2023 and no later than 2026  (Kitiashvili’s Prediction 2024 – 2025), with a minimum peak sunspot number of 95 and a maximum of 130 (Kitiashvili’s Prediction 50).  In addition, the panel expects at NOAA state the end of Cycle 24 and start of Cycle 25 to occur no earlier than July, 2019, and no later than September, 2020.  The panel hopes to release a final, detailed forecast for Cycle 25 by the end of 2019.  Please read the official NOAA press release describing the international panel’s forecast at https://www.weather.gov/news/190504-sun-activity-in-solar-cycle & Here

This chart is from David Birch an independent solar researcher. Here you can clearly see the low activity around the times of 1790 and ended in December 1830. According to NASA’s next cycle will hit 50 for the MAX!!!

It will be interesting to see how Valentina Zharkova’s works stacks up against these two predictions!  STAY TUNED!!
