A major solar flare measuring X1.1 erupted from Active Region (AR) 3947 at 22:41 UTC on January 3, 2025. The event started at 22:32 and ended at 22:51 UTC. This is the second X-class solar flare produced on January 3 \u2014 both from AR 3947. Meanwhile, CME produced on January 1 impacted Earth early January 4, sparking G1 \u2013 Minor geomagnetic storm.<\/strong><\/p>\n<\/div>\n

A Type II Radio Emission, with estimated velocity of 465 km\/s was detected at 22:44 UTC, suggesting a coronal mass ejection (CME) is associated with the flare event.<\/p>\n

Radio frequencies were forecast to be most degraded over the Pacific Ocean at the time of the flare.<\/p>\n

This is the second X-class solar flare of the day, following X1.2 at 11:39 UTC from the same region \u2014 AR 3947 (beta-delta).<\/p>\n

The X1.2 event resulted in an easterly CME that was first visible in NASA C2 coronagraph imagery near 12:00 UTC. \u201cHowever, analysis and modeling have determined this event to be well off the Sun-Earth line,\u201d SPWC forecasters said. <\/p>\n

Four M-class were produced following the X1.1 late January 3, including M5.8 at 23:56 UTC and M7.6 at 05:18 UTC on January 4 \u2014 all from AR 3947.<\/p>\n

A CME produced on January 1 was detected at DSCOVR spacecraft at Sun-Earth L1 Lagrange point \u2014 about 1.5 million km (1 million miles) from Earth, at 02:11 UTC on January 4.<\/p>\n

This was a glancing blow that sparked G1 \u2013 Minor geomagnetic storming over the next couple of hours.<\/p>\n

There are currently 11 sunspot regions on the Earth side of the Sun.<\/p>\n

Solar activity is expected to remain at moderate to high levels over the next 3 days, with 55% chance of M-class flares and 10 \u2013 15% chance of X-class.<\/p>\n

There\u2019s a slight chance for S1 \u2013 Minor solar radiation storm through January 6.<\/p>\n

Isolated periods of G1 \u2013 Minor geomagnetic storming are likely today and tomorrow due to combined effects of CME and positive polarity coronal hole high speed stream (CH HSS).<\/p>\n
