Solar activity was at low levels. The largest flare was a C6.6/SF flare from Region 4345 (S17E56, Cro/beta). Region 4341 (S11E48, Dkc/beta-gamma-delta) remained the mostly complex region on the disk but was mostly quiet over the past 24 hours. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low with M-class flares likely (R1-R2, Minor-Moderate) and a slight chance for X-class flares (R3-Strong) on 16-18 Jan mainly due to the flare potential of AR 4341. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels with a peak flux of 9,010 pfu at 15/1645 UTC. The greater than 10 MeV proton flux remained at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue to reach high levels on 16 Jan. A brief return to moderate levels on 17 Jan is likely with the arrival of a positive polarity CH HSS. High levels are expected to return on 18 Jan. The greater than 10 MeV proton flux is expected to remain at background levels. Solar Wind .24 hr Summary... Solar wind parameters were elevated, likely due to transient activity. An increase in solar wind speeds from ~550 km/s to a peak of ~700 km/s began after 16/0214 UTC. Total magnetic field strength increased from ~5 nT to 13 nT. The Bz component of the IMF was oriented primarily northward with the exception of a brief rotation southward to 11 nT around 16/0327 UTC. .Forecast... Weak CME influence is expected to subside through 16 Jan. Another enhancement in the solar wind is expected over 17-18 Jan when a recurrent, positive polarity CH HSS is expected to become geoeffective. Solar wind speed is likely to exceed 700 km/s based on recurrence data. Geospace .24 hr Summary... The geomagnetic field was quiet to active levels. .Forecast... Quiet to active levels are expected on 16 Jan due to residual CME effects. Over 17-18 Jan, a positive polarity CH HSS is expected to be geoeffective, causing unsettled to G1 (Minor) storming, with a chance for G2 (Moderate). ####018002108#### FXXX10 KWNP 161543 DAYTDF :Product: 3-Day Forecast :Issued: 2026 Jan 16 1234 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # 3-Day Forecast # A. NOAA Geomagnetic Activity Observation and Forecast The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA Scale levels). The greatest expected 3 hr Kp for Jan 16-Jan 18 2026 is 5.33 (NOAA Scale G1).

B. NOAA Solar Radiation Activity Observation and Forecast Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was below S-scale storm level thresholds. Solar Radiation Storm Forecast for Jan 16-Jan 18 2026 Jan 16 Jan 17 Jan 18 S1 or greater 5% 5% 5% Rationale: No S1 (Minor) or greater solar radiation storms are expected. No significant active region activity favorable for radiation storm production is forecast. C. NOAA Radio Blackout Activity and Forecast No radio blackouts were observed over the past 24 hours. Radio Blackout Forecast for Jan 16-Jan 18 2026 Jan 16 Jan 17 Jan 18 R1-R2 55% 55% 55% R3 or greater 10% 10% 10% Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a slight chance for R3 (Strong), over 16-17 Jan. ####018000581#### AXXX80 KWNP 161543 DAYEVT :Product: Space Weather Event Reports dayevt.txt :Issued: 2026 Jan 16 0245 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # Space Weather Event Reports # :Energetic_Solar_Events: 2026 Jan 15 #Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1727 1727 1727 110 2024 2024 2024 360
