(last updated 06 Jan 2026 23:30 UT)
07 Jan 08 Jan 09 Jan Activity R1, chance R2 R1, chance R2 R1 Fadeouts Possible Possible Possible 10.7cm/SSN 140/94 135/89 132/86 COMMENT: Solar flare activity on UT day 06-Jan was at the R0 level, with no significant flare activity observed over the past 24 hours. There are currently six active regions on the Sun, with Active Region (AR) 4336 (S09E55, beta-gamma) being the largest. This region recently rotated onto the disk. This region has grown slightly in size and shows flaring potential. AR 4334 (S15E40, beta-gamma) has also shown some mild growth and East-West separation. All other regions are either stable or in decay. Four regions are expected to rotate off disk over the 07-09 Jan, being AR 4323, 4324, 4325 and 4333. Solar flare activity is forecast to reach the R1 level, with a chance of R2 over 07-08 Jan due to the past flare activity of AR 4325 and 4324 (N26W52, alpha). This will decline to R1 for the 09-Jan, as a number of regions rotate of disk. S0 solar radiation storm conditions were observed over the past 24 hours, with the proton flux at background levels. S0 conditions are forecast to persist over the period 07-09 Jan. No new geoeffective Coronal Mass Ejections (CMEs) were observed over the past UT day. The solar wind speed was stable over the 06-Jan, ranging between 400 - 340 km/s. It is likely to remain at this level until the arrival of a Coronal Hole High Speed Wind Stream, on approximately the 09-Jan. The interplanetary magnetic field strength (IMF, Bt) peaked at 8 nT during 06-Jan, with the North-South component (Bz) ranging between -6 and +6 nT during this time. While much of the 06-Jan experienced southward Bz, this component began to increase at approximately 1100 UTC. Since then, Bz has been largely positive.
