An X4.1 flare (SIDC flare 6063) was registered by GOES-19 as peaked on 14 Nov at 08:30 UTC. The source was SIDC Sunspot Group 687 (NOAA Active Region 4274). A proton event associated with this eruption is currently recorded by GOES-19. A Coronal Mass Ejection (CME) is likely to occur, however considering the location of the X-flare, it is currently uncertain if it will affect Earth and how strong the effect will be.

A class X4.0 solar X-ray flare occurred on 2025/11/14 with peak time 08:30UT

A halo or partial-halo CME was detected with the following characteristics: t0 | dt0| pa | da | v | dv | minv| maxv| 2025-11-14T07:48:07.418 | 3.0 | 336 | 190 | 946 | 305 | 400 | 1736 t0: onset time, earliest indication of liftoff dt0: duration of liftoff (hours) pa: principal angle, counterclockwise from North (degrees) da: angular width of the CME (degrees), v: median velocity (km/s) dv: variation (1 sigma) of velocity over the width of the CME mindv: lowest velocity detected within the CME maxdv: highest velocity detected within the CME

Solar flaring activity was high over the past 24 hours, with an X4.1 flare (SIDC flare 6063) observed on 14 Nov at 08:30 UTC. SIDC Sunspot Group (SG) 687 (NOAA Active Region [AR] 4274, Beta-Gamma-Delta magnetic configuration) produced the said flare together with the majority of the flaring activity. SIDC SG 689 (NOAA AR 4276, Beta magnetic configuration) produced the rest of the C-class flaring activity. In the next 24 hours isolated M-class flares are likely to occur from SIDC SG 687 and there is a small chance of another X-class flare from the same SG/AR. SIDC flare 6063 (an X4.1 flare emitted on 14 Nov at 08:30 UTC) has caused a Coronal Mass Ejection (CME) that can potentially impact Earth. However, there are not yet enough observations available for a meaningful forecast. More information will be provided in the next Ursigram. SIDC Coronal Hole 126 (mid-latitude coronal hole with a negative polarity) first reached the central meridian on November 13. It is expected to produce a High Speed Stream (HSS) that will become geo-effective on 17 Nov. During the past 24 hours the greater than 10 MeV proton flux, as measured by the GOES-19 satellite, dropped bellow the 10 pfu threshold level on 13 Nov at 15:00 UTC. However, SIDC flare 6063 (an X4.1 flare) cause another proton even and the greater than 10 MeV proton flux exceeded again the 10 pfu alert threshold on 14 Nov 09:20 UTC. The new proton event is relatively weak hence the greater than 10 MeV proton flux is not expected to increase much further in the next 24 hours, rather stay close to the 10 pfu level. The greater than 2 MeV electron flux as measured by GOES 19 was below but close to the 1000 pfu alert threshold during the past 24 hours. It is expected to increase in the next 24 hours and possibly cross the alert threshold. The 24-hour electron fluence was at moderate levels during the past 24 hours. It is expected to remain at moderate levels in the next 24 hours.

The global geomagnetic conditions were at the minor storm level (NOAA Kp 5) on 13 Nov from 12:00 to 15:00 UTC. For the rest of the past 24 hours they fluctuated between quiet and active conditions (NOAA Kp 1- to 4). The local geomagnetic conditions were also varying between quiet and active levels (K BEL 1 to 4) but did not register stormy conditions at any interval. For the next 24 hours both the global and local geomagnetic conditions are expected to range between quiet and unsettled levels. During the past 24 hours the Solar Wind (SW) conditions moved towards a slow SW regime. The SW speed dropped from a peak at 880 km/s to 580 km/s. The interplanetary magnetic field (B) also dropped, from a peak of 11 nT to 4 nT, and its North-South component (Bz) fluctuated between -3 nT and 9 nT at the second half of 13 Nov, but now registers values around 5 nT. For the next 24 hours the SW conditions are expected to reach slow SW levels.
