Space Weather Message Code: SUM10R Serial Number: 628 Issue Time: 2014 Sep 11 1543 UTC SUMMARY: 10cm Radio Burst Begin Time: 2014 Sep 11 1523 UTC Maximum Time: 2014 Sep 11 1523 UTC End Time: 2014 Sep 11 1525 UTC Duration: 2 minutes Peak Flux: 210 sfu Latest Penticton Noon Flux: 160 sfu Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications. Space Weather Message Code: WARPC0 Serial Number: 79 Issue Time: 2014 Sep 11 1133 UTC CANCEL WARNING: Proton 100MeV Integral Flux above 1pfu expected Cancel Serial Number: 78 Original Issue Time: 2014 Sep 10 2322 UTC Comment: Conditions no longer exist to warrant this warning. Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact. Space Weather Message Code: SUMPC0 Serial Number: 27 Issue Time: 2014 Sep 11 1124 UTC SUMMARY: Proton Event 100MeV Integral Flux exceeded 1pfu Begin Time: 2014 Sep 11 0425 UTC Maximum Time: 2014 Sep 11 0425 UTC End Time: 2014 Sep 11 0535 UTC Maximum 100MeV Flux: 1 pfu Comment: Maximum 1000MeV Flux 1.25 pfu Space Weather Message Code: ALTK04 Serial Number: 1722 Issue Time: 2014 Sep 11 0526 UTC ALERT: Geomagnetic K-index of 4 Threshold Reached: 2014 Sep 11 0522 UTC Synoptic Period: 0300-0600 UTC Active Warning: Yes Potential Impacts: Area of impact primarily poleward of 65 degrees Geomagnetic Latitude. Induced Currents - Weak power grid fluctuations can occur. Aurora - Aurora may be visible at high latitudes such as Canada and Alaska. Space Weather Message Code: WATA50 Serial Number: 50 Issue Time: 2014 Sep 11 0459 UTC WATCH: Geomagnetic Storm Category G3 Predicted Highest Storm Level Predicted by Day: Sep 12: G2 (Moderate) Sep 13: G3 (Strong) Sep 14: G1 (Minor) THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT Comment: Upgrading the Watch for 13-14 Sep due to anticipated effects from the CME associated with yesterdays R3 (Strong) event. Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude. Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices. Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur. Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur. Radio - HF (high frequency) radio may be intermittent. Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. Space Weather Message Code: ALTPC0 Serial Number: 42 Issue Time: 2014 Sep 11 0431 UTC ALERT: Proton Event 100MeV Integral Flux exceeded 1pfu Begin Time: 2014 Sep 11 0425 UTC Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact. Space Weather Message Code: WARK04 Serial Number: 2312 Issue Time: 2014 Sep 11 0330 UTC WARNING: Geomagnetic K-index of 4 expected Valid From: 2014 Sep 11 0330 UTC Valid To: 2014 Sep 11 1300 UTC Warning Condition: Onset Potential Impacts: Area of impact primarily poleward of 65 degrees Geomagnetic Latitude. Induced Currents - Weak power grid fluctuations can occur. Aurora - Aurora may be visible at high latitudes such as Canada and Alaska. Space Weather Message Code: ALTPX1 Serial Number: 309 Issue Time: 2014 Sep 11 0247 UTC ALERT: Proton Event 10MeV Integral Flux exceeded 10pfu Begin Time: 2014 Sep 11 0240 UTC NOAA Scale: S1 - Minor Potential Impacts: Radio - Minor impacts on polar HF (high frequency) radio propagation resulting in fades at lower frequencies.
