Prediction for CME (2014-01-30T16:24:00-CME-001)CME Observed Time: 2014-01-30T16:24ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/4539/-1 CME Shock Arrival Time: 2014-02-02T23:18Z Observed Geomagnetic Storm Parameters due to CME: Max Kp: 2.0 Predicted Arrival Time: 2014-02-02T04:00Z Predicted geomagnetic storm max Kp range due to CME: 5.0 - 5.0 Prediction Method: WSA-ENLIL + Cone (NOAA/SWPC) Prediction Method Note: Arrival Prediction by NOAA/SWPC submitted to this system by M. Leila Mays) (Submitted CME shock arrival time taken from simulation posted here: http://www.swpc.noaa.gov/wsa-enlil/) (Submitted Kp estimate is from the Forecast Discussion and 3-Day Forecast below) -- Product: Forecast Discussion Issued: 2014 Feb 01 0030 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center Solar Activity .24 hr Summary... Solar activity reached moderate levels with an M1 flare from Region 1968 (N10E29, Eai/beta-gamma) at 31/1542 UTC. The flare was accompanied by dimming in SDO/AIA 193 imagery between 31/1535-1612 UTC to the southeast of the region and between 31/1624-1705 UTC north of the region. A coronal mass ejection (CME) was visible in SOHO/LASCO C2 coronagraph imagery emerging from the southeast at approximately 31/1602 UTC followed by a second eruption to the northeast at 31/1624 UTC. Preliminary analysis suggested the eruption to the northeast was moving at approximately 400-500 km/s. Further analysis and modeling will be undertaken once sufficient coronagraph imagery becomes available. Consolidation and flux emergence was evident in the intermediate portion of Region 1967 (S14E29, Fkc/beta-gamma-delta) while Region 1968 grew slightly and developed a beta-gamma configuration. .Forecast... Solar activity is likely to be moderate (R1-Minor to R2-Moderate) with a slight chance for an X-class flare (R3-strong) during the period (01-03 Feb). Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels. The greater than 10 MeV proton flux at geosynchronous orbit was at background levels. .Forecast... The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels with a chance for moderate levels for the forecast period (01-03 Feb). The greater than 10 MeV proton flux at geosynchronous orbit is expected to be at background levels (below S1-Minor), but the threat of a proton event will be increasing as Region 1967 crosses the central meridian. Solar Wind .24 hr Summary... The solar wind environment at ACE was nominal. Speed at the ACE spacecraft reached 376 km/s at 31/0319Z. Total IMF reached 6 nT at 31/0404Z. The maximum southward component of Bz reached -3 nT at 31/0929Z. .Forecast... Solar wind parameters are expected to continue at nominal levels through approximately mid day on Day 2 (02 Feb), when a glancing blow from the 30 Jan CME is expected to enhance the solar wind. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... The geomagnetic field is expected to be mostly quiet on day 1 (01 Feb). A glancing blow from the 30 Jan CME is expected to arrive around mid-day on day 2 (02 Feb) causing unsettled to minor storm (G1-Minor) conditions. Three CME characterizations and WSA-Enlil model runs were conducted. The run with the most westerly origin brought the CME in late on 01 Feb, representing the earliest possible arrival. The run with the lowest speed brought the CME in almost 24 hours later. -- Product: 3-Day Forecast Issued: 2014 Feb 01 0030 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center A. NOAA Geomagnetic Activity Observation and Forecast The greatest observed 3 hr Kp over the past 24 hours was 1 (below NOAA Scale levels). The greatest expected 3 hr Kp for Feb 01-Feb 03 2014 is 5 (NOAA Scale G1).
