On the night of June 19, another X-class flare occurred on the Sun – a twin brother of the one that occurred on June 17. The AR4114 group of spots again showed its “willful character”. At 23:50 UTC, the energy of the flare reached X1.91, which is only slightly more powerful than the last one.
⚡️X marks the spot… AGAIN! ⚡️
AR4114 is back at it with a fiery X1.9 flare at 23:50 UTC on June 19! 🔥
This region takes a lickin’ and keeps on tickin’—truly the Energizer Bunny of sunspots. 🐰☀️

Like two days ago, this flare was not accompanied by a notable coronal mass ejection (CME), which means we won’t be having any magnetic storms or auroras anytime soon.
Solar flares are thought to be caused by the reclosure of magnetic field lines, which releases large amounts of energy. Solar flares are thought to be caused by the redirection of magnetic field lines, which releases large amounts of energy. But the apparent power of a flare is also related to how deep this redirection occurs. There is no direct relationship between flare energy and CME: there are very powerful flares with no emission, as well as more modest (previous M-class) flares accompanied by spectacular plasma emission.
Although AR4114 still has a complex magnetic structure, and hence the potential for flares, due to the sun’s spin, it is slowly moving out of our field of view and will disappear completely in a few days. If an ejection does occur from this region over the next few days, it will mostly pass by Earth.
