STRANGELY-MAGNETIZED SUNSPOT: There's something strange about sunspot AR3536. Its magnetic field is cockeyed. This magnetic map from NASA's Solar Dynamics Observatory shows what we mean:  All sunspots have two magnetic poles, plus (+) and minus (-). They're supposed to be oriented side-by-side, like this: . Instead, the magnetic field of AR3536 is perpendicular to normal: . This twist may explain why the sunspot is so active. Twisted magnetic fields harbor extra energy for solar flares. In the past 2 days, AR3636 has unleashed four M-class flares and an X5-class flare that ranks as the most powerful explosion of Solar Cycle 25 (so far). If this strange magnetization persists, more flares may be in the offing. Stay tuned! |

"more flares may be in the offing" is a very intriguing statement ... what do you suppose it means? |

I believe the last sun spot and big eruption that caused the Northern light show disrupted the power at my house. I had to reset some things after the power went out for a moment at about 2:15 AM. I remember in Cupertino CA one year (1980s) there was a power surge that fried some electronic equipment for about 1 mile. the power surge even blew out a transformer. the recent one was about a few weeks ago at my house. most of my equipment is surge protected but not all backed up with power supplies. |
