Watch these presentations that are safe from harmful rays of bright light from the Sun. Don't be surprised if there's an X-flare today. Big sunspot AR3712 (as seen at the 5 o’clock relative position) has a mixed-polarity magnetic field with north (+) and south (-) poles bumping together. Magnetic reconnection could soon cause a strong explosion. The sunspot is directly facing Earth, so any flares will be geo-effective.
