“First Traces” Of Solar Cycle 26 Detected On Sun\u00a0<\/span><\/p>\n

\n

Scientists from the\u00a0University of Birmingham in England have detected the “first rumblings”\u2014or first indications\u2014that the sun’s next 11-year solar cycle, Cycle 26, will begin by the decade’s end.<\/p>\n

The current cycle, Cycle 25, has reached what scientists call a “solar maximum<\/a>,” when the sun’s magnetic field flips and its poles swap places. This peak is known for elevated solar activity, including sunspots, flares, and coronal mass ejections.<\/p>\n

Researchers from\u00a0Birmingham recently\u00a0presented<\/a> the new data\u00a0at the Royal Astronomical Society’s National Astronomy Meeting in Hull. The data shows the first signs that the next solar cycle is\u00a0beginning.\u00a0<\/p>\n

Astronomers use the sun’s internal sound waves to measure how it rotates, making visible a pattern of bands (solar torsional oscillation) that rotate slightly faster or slower. These move towards the sun’s equator and its poles during the activity cycle.<\/em><\/p>\n

The faster-rotation belts tend to show up before the next solar cycle officially begins. -researchers\u00a0<\/em><\/p>\n

Research leader Rachel Howe from\u00a0Birmingham noted a ‘faint indication’\u00a0is beginning to show up after analyzing the pattern of the sun’s\u00a0bands (solar torsional oscillation). The\u00a0faster-rotation belts tend to show up before the next solar cycle arrives.\u00a0<\/p>\n

“If you go back one solar cycle –\u00a011 years –\u00a0on the plot, you can see something similar that seems to join up with the shape that we saw in 2017. It went on to be a feature of the present solar cycle, Cycle 25,” said Dr. Howe.<\/p>\n

This map shows which latitudes on the Sun were rotating faster (shown in red and yellow) or slower (shown in blue and green) than average over the last 29 years, as inferred by helioseismology (the analysis of solar sound waves). For each solar cycle, there is a band of faster rotation that moves down towards the equator. The yellow lines show the areas where the magnetic fields are most concentrated.<\/a><\/p>\n

She said, “We’re likely seeing the first traces of Cycle 26, which won’t officially start until about 2030.”<\/p>\n

It is possible to see the whole of Solar Cycles 23 and 24, and the first half of Cycle 25. For each cycle, the band of faster rotation starts well before the magnetic activity for that cycle. On the far right of the figure, a bit of red marks what the team believes is the beginning of the fast-rotating band for Cycle 26. Rachel Howe<\/a><\/p>\n

Researchers have been analyzing\u00a0solar torsional oscillation patterns on the sun using\u00a0helioseismic data from the Global Oscillation Network Group (GONG), the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory, and the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory since the mid-1990s. This data now covers Solar Cycles 23, 24, and 25, allowing researchers better to understand the precursors to the next solar cycle.\u00a0<\/p>\n

Howe has been a student of the stars for 25 years, studying the sun’s\u00a0rotation through\u00a0GONG and MDI data.\u00a0<\/p>\n

“With more data, I hope we can understand more about the part these flows play in the intricate dance of plasma and magnetic fields that form the solar cycle,” she concluded.<\/p>\n

Several studies (one here<\/a>) have suggested the sun will experience a new\u00a0grand solar minimum between 2030 and 2040. This could decrease solar activity,\u00a0similar to the Maunder minimum in the 17th century. At that time,\u00a0Earth experienced a period of global cooling known as the Little Ice Age.\u00a0<\/p>\n

But in the meantime, the Tonga eruption<\/a> in 2022 appears to have fueled global warming, not cow farts or Taylor Swift’s private jet.<\/p>\n<\/div>\n
