April 16, 2021: You probably think Solar Cycle 25 is a dud. The scope of the review is further restricted to the issue of predicting the amplitude (and In a press event, experts from the panel, NASA, and NOAA discussed the analysis and Solar Cycle 25 prediction, and how the rise to the next solar maximum and subsequent upswing in space weather will impact our lives and technology ⦠They announced on December 7, 2020, their prediction that Solar Cycle 25 will be one of the strongest on record. The new solar cycle, Solar Cycle 25, officially began in December 2019. The bottom plot: The summary curve derived from the two PCs above for the âhistoricalâ data (cycles 21 - 23) and predicted for solar cycle 24 (2008 - 2019), cycle 25 (2020 - 2031), cycle 26 (2031 - 2042). Zharkova was one of only two scientists to correctly predict solar cycle 24 would be weaker than cycle 23 â in fact, only 2 out of 150 models predicted this. Scientists charged with predicting the Sunâs activity for Cycle 25 say itâs likely to be much like that of current Cycle 24, which is declining and predicted to bottom out in 2019 or 2020. Solar Cycle 25 only began in December 2019âafter the weakest solar cycle in 100 yearsâso itâs early days, but things appear to be hotting-up ⦠September 15, 2020 - The solar minimum between Solar Cycle 24 and 25 - the period when the sun is least active - happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8, according to the Solar Cycle 25 Prediction Panel, co-chaired by NOAA and NASA. The NOAA/NASA co-chaired, international panel to forecast Solar Cycle 25 released their latest forecast for Solar Cycle 25. Solar cycle 25 prediction, NOAA. Figure 10 indicates that the amplitude of Solar Cycle 25 will be close to that of Solar Cycle 24. In this plot, the red curve shows NOAAâs predicted sunspot counts for Solar Cycle 25⦠NOAA predicts Solar Cycle 25 will max out at 114.6 sunspots in July, 2025 (note this is far higher than NASAâs official prediction of around 30 to 40 sunspots). Figure 2| The 38 predictions of Solar Cycle 25 that had been registered by January 2020 (Adapted after Ref [4] with permission). Solar Cycle 24, which began in December 2008 and is likely to end in 2020, was smaller in magnitude than the previous two cycles. Solar Cycle 24 and 25 F10.7 Flux Prediction.The data used to make these plots are located in this text file. The sun's activity has been slowly increasing since then and is expected to peak in July 2025. The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced that solar minimum occurred in December 2019, marking the start of a new solar cycle. September 15, 2020 â The solar minimum between Solar Cycle 24 and 25 â the period when the sun is least active â happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8, according to the Solar Cycle 25 Prediction Panel, co-chaired by NOAA and NASA. In regard to his most recent research he gave a Zoom presentation to the Front Range 6 Meter group on 11-November-2020. The panel agreed that Cycle 25 will be average in intensity and similar to Cycle 24. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum - the period when the Sun is least active - late in 2019 or 2020. Solar Cycle 25 has begun. We are now in Solar Cycle 25 with peak sunspot activity expected in 2025, the panel said. Many solar cycle researchers think that cycle 25 will start late 2019 or even in 2020-2021. The Author(s) 2020 Abstract A review of solar cycle prediction methods and their performance is given, including early forecasts for Cycle 25. And only after that will the sun slide into a Grand Solar Minimum. Our prediction (128±10) is indicated by the yellow âsunâ in the center of the plot, near the average (123±21) of the 6 (now 7) precursor methods that seem to be preferred. The review focuses on those aspects of the solar cycle prediction problem that have a bearing on dynamo theory. We have used our AFT code to predict the amplitude and hemispheric asymmetry of the Sunâs polar magnetic fields at the start of 2020, approximately the next cycle minimum. This figure is from the Wilcox Solar Observatory. New sunspot cycle could be one of the strongest on record, new research predicts: Scientists use an extended, 22-year solar cycle to make the forecast. Analysis determines we are in Solar Cycle 25. The solar polar field strength at solar minimum is the most accurate predictor of the amplitude of the following solar cycle. (Figure 3) Solar activity (summary) curve restored for 1200 - 3300 AD. Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. A NOAA/NASA co-chaired international panel â charged with forecasting the upcoming 11-year solar cycle, Solar Cycle 25 â released a preliminary forecast on ⦠Experts on the Solar Cycle 25 Prediction Panel recently announced that the Sun has officially entered a new cycle, its 25th since weâve had enough data to reliably recognise them. Zharkovaâs models have run at a 97% accuracy and now suggest a Super Grand Solar Minimum is on the cards beginning 2020. However, after analyzing the lowest adjusted 10.7cm solar flux values, we find that the adjusted flux for November 2018 is low enough to give the start of solar cycle 25 between October 2018 and February 2019, November 2018 being most likely. Solar Cycle 25 is here, ushering in the next season of space weather from the Sun. Download. Despite long stretches of spotless quiet, the new solar cycle is actually running ahead of schedule. Unlike most forecasts for solar Cycle 25, ... " The possibility of a smoothed sunspot number (SSN) reaching as high as 305 is in the prediction! Like. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum - the period when the Sun is least active - late in 2019 or 2020. Because our Sun is so variable, it can take months after the fact to declare this event. "How quickly solar activity rises in an indicator of how strong the cycle will be," said Doug Biesecker, Ph.D., panel co-chair and a solar physicist at NOAAâs Space Weather Prediction ⦠Solar Cycle Update. 04/08/2019. Experts on the Solar Cycle 25 Prediction Panel recently announced that the sun has officially entered a new cycle, its 25th since we've had enough data to reliably recognize them. Figure 10: Solar polar field strength 1975 â 2020. More information: Scott W. McIntosh et al, Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude, Solar Physics (2020⦠The title of Dr. McIntoshâs talk was âSolar Cycle 25 Prediction and Why It Will Be Huge!â The prediction he made for the amplitude of Solar Cycle 25 ⦠Details Related. Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. You have already liked this page, you can only like it once! A physics-based prediction relying on the data-driven solar dynamo and solar surface flux transport models by Bhowmik and Nandy (2018) seems to have predicted the strength of the solar polar field at the current minima correctly and forecasts a weak but not insignificant solar cycle 25 similar or slightly stronger in strength relative to cycle 24. As our starâs activity ramps upâa natural part of its roughly 11-year cycleâscientists are eager to test their predictions. Since the start of 2020, activity on the Sun has steadily increased, indicating we transitioned to Solar Cycle 25. (2020, December 7). Additionally, the panel concurred that solar minimum between Cycles 24 and 25 will occur in April, 2020 (+/- 6 months). Between 2023 and 2025, the sun will reach its maximum activity, after which it will decrease again around 2027. 29/10/2020 984 views 8 likes 443976 ID. We have reviewed recent investigations related to prediction of the amplitude of Solar Cycle 25 and these are summarized in Table 4. Think again. Petrovay, 2020 for details). The Solar Cycle 25 Prediction Panel announced solar minimum occurred in December 2019, marking the transition into a new solar cycle. Tracking the solar cycle is a key part of better understanding the sun and mitigating its impacts on human technology and infrastructure. Discover the Cycle 24 Polar Field Predictions! We just started solar cycle 25 âin December 2020â and the solar activity is only now on the rise. The success of these predictions will depend upon an upcoming terminator event before the end of 2020. The article below, by Laura Snider, ⦠The SSN values indicate that the cycle 25 will be stronger than cycle 24 and a little weaker than cycle 23, even if the current solar cycle minimum occurs in 2021 instead of 2020. If the solar minimum prediction is correct, this would make Solar Cycle 24 the 7 th longest on record (11.4 years). The updated prediction is 134 ± 11 or 131 ± 11 on the revised SSN V2.0 scale assuming the cycle 24 minimum to occur in 2020 or 2021, respectively. During periods of low solar activity such as this modern GSM the Sun will often be devoid of sunspots. The Sun has just completed solar cycle 24 â the weakest solar cycle in the past 100+ years â and 2020 saw the beginning of solar cycle 25. An over-simplification of the methodologies used to develop their prediction describes the study of the complex relationship involving the Sun's 22-year (Hale) magnetic cycle, the end points of adjoining cycles called 'terminations' and sunspot production, to predict the eventual strength of the new cycle. During the teleconference, experts on the Solar Cycle 25 Prediction Panel will discuss recent updates in solar cycle progress, and the forecast for the upcoming cycle, Solar Cycle 25. On occasion, researchers have predicted that coming solar cycles may also exhibit extended periods of minimal activity. Right now, researchers hope to mark a formal end to Cycle 24 in 2021 to make a definitive prediction of solar cycle 25 amplitude. Our result is in agreement with the preliminary forecast for Solar Cycle 25 on 9 December 2019 by an international panel co-chaired by NOAA/NASA and many other recent investigations (e.g. HI-RES JPG [35.31 kB] Thank you for liking.
