The most powerful solar eruption since the beginning of this activity cycle was recorded on July 26 at 01:00 UTC by the Solar Orbiter (SolO) satellite. This eruption occurred in an active region on the Sun that is currently on the far side of the Sun and cannot be seen from Earth. Therefore, this powerful eruption will not have a significant impact on Earth.
This eruption was classified as X14. It's worth mentioning that the largest eruption ever recorded occurred on November 4, 2003, and was classified as X28 (with the energy of 0.0028 watts per square meter) on the flare intensity scale. However, it is believed that it was even stronger (somewhere between X40 and X45) because the detector became saturated, so it could only measure up to this value of X-ray radiation.
