1 Time and Date Standards Space Weather EOC SWEOC "Providing Quick Reference Solar Information" All images and plots are time stamped with UTC (GMT) date and time. Use these references to check your time and date and synchronize with NIST time. Your system time & date: 12:22:44 on Wednesday, November 19, 2014 Adjust this NIST Clock to 24 Hour-UTC to coordinate with images and data plots if required This widget is a public service provided by the Time and Frequency Division of the National Institute of Standards and Technology (NIST). It is a web clock showing the official time of day from NIST, displayed as a 12 or 24-hour clock, in a user-selectable time zone. The time reference for the widget is the output of the national time scale called UTC(NIST). It starts with a zero-offset time zone called Coordinated Universal Time (UTC), and it is adjusted to the local time based on the client's computer time zone settings. It is not continuously linked to NIST - it re-synchronizes with NIST every 10 minutes. Therefore. this widget is intended as a time-of-day service only. It should not be used to make measurements, nor should it be used to establish traceability to NIST. The widget utilizes the client's computer clock as a timer to measure the round-trip network delay, which is the interval of time starting when the widget sends a time request to the server and ending when the time is displayed in the browser. The accuracy of the time shown will always be better than this round-trip delay. Website: The information and links on this page are provided to you as a quick reference to government and private organizations that monitor atmospheric and space environment conditions. They are structured to be presented on an EOC center computer monitor or projection screen to provide precise and timely data on global conditions that effect radio and electrical systems. Should you encounter links that do not work properly or have questions please use the special message link below. Space Weather EOC Information Kit 11/19/20146:30:15 PM Page 1 of 14

SDO Website: Technical Reference: GOES 13 and GOES 15 Data Plots The six data plots at the left provide continuous satellite altitude monitoring that measure the sun's influence on the atmosphere. Each plot describes the measurement time interval from 1 minute to 3 hours. The time period is detailed at the bottom of each plot. All link to the NWS SWPC website. Some of the plots show actual minimum and maximum period measurements. From this data you can monitor trends. The 1 minute -Ray plot will give the first indications of a solar flare. The 1 minute Magnetometer plot will give the first indications of a CME in progress. full screen after the page loads and F11 again to restore your screen.

Data from the SWPC Primary GOES -ray satellite is shown. As Space Weather EOC Information Kit 11/19/20146:30:15 PM Page 3 of 14

4 of Feb 2008, no Secondary GOES -ray satellite data is available. Some data dropouts will occur during satellite eclipses. During the spring and fall, GOES satellites experience eclipses in which the Earth or moon blocks the -ray instrument view to the sun for a short period every day. Eclipse season lasts for about 45 to 60 days and ranges from minutes to just over an hour. At these times there is a gap in the RS signal shown. Other plots of interest: 3-day GOES 5-min -rays; SWPC Real-time Monitors. SWPC -ray alerts are issued at the M5 (5x10E-5 Watts/m2) level, based upon 1-minute data. Large -ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. Some large flares are accompanied by strong solar radio bursts that may interfere with satellite downlinks. This page updates dynamically every minute. Webpage: GOES 5-minute averaged integral proton flux (protons/cm2-s-sr) as measured by the SWPC primary GOES satellite for energy thresholds of >=10, >=50, and >=100 MeV. SWPC's proton event threshold is 10 protons/cm2-s-sr at >=10 MeV. Large particle fluxes have been associated with satellite single event upsets (SEUs). This page updates dynamically every 5 minutes.

5 The GOES -ray Flux plot contains 5 minute averages of solar -ray output in the 1-8 Angstrom ( nm) and Angstrom ( nm) pass bands. Data from the SWPC Primary and Secondary GOES -ray satellites are shown. Some data dropouts from the Primary satellite will occur during satellite eclipses. Other plots of interest: A black background version of this plot; GOES 1-min -rays; SWPC Real-time Monitors. SWPC -ray alerts are issued at the M5 (5x10E-5 Watts/m2) and 1 (1x10E-4 Watts/m2) levels, based upon 1-minute data. Large -ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. Some large flares are accompanied by strong solar radio bursts that may interfere with satellite downlinks. This page updates dynamically every 5 minutes. Webpage: The Estimated 3-hour Planetary Kp-index is derived at the NOAA Space Weather Prediction Center using data from the following ground-based magnetometers: Sitka, Alaska; Meanook, Canada; Ottawa, Canada; Fredericksburg, Virginia; Hartland, UK; Wingst, Germany; Niemegk, Germany; and Canberra, Australia. These data are made available thanks to the cooperative efforts between SWPC and data providers around the world, which currently includes the U.S. Geological Survey, Natural Resources Canada (NRCAN), the British Space Weather EOC Information Kit 11/19/20146:30:15 PM Page 5 of 14

6 Geological Survey, the German Research Centre for Geosciences (GFZ), and Geoscience Australia. Important magnetometer observations are also contributed by the Institut de Physique du Globe de Paris and the Korean Space Weather Center Other SWPC Real-time Monitors Kp-indices of 5 or greater indicate storm-level geomagnetic activity. Geomagnetic storms have been associated with satellite surface charging and increased atmospheric drag. For more information see The K-index or SWPC Education page. This page updates dynamically every 5 minutes. Webpage: The GOES Hp plot contains the 1-minute averaged parallel component of the magnetic field in nanoteslas (nt), as measured at GOES-13 (W75) and GOES-15 (W89). The Hp component is perpendicular to the satellite orbit plane and Hp is essentially parallel to Earth's rotation axis. If these data drop to near zero, or less, when the satellite is on the dayside it may be due to a compression of Earth's magnetopause to within geosynchronous orbit, exposing satellites to negative and/or highly variable magnetic fields. On the night side, a near zero, or less, value of the field indicates strong currents that are often associated with substorms and an intensification of currents in the Earth's geomagnetic tail. Noon and midnight local time at the satellite are plotted as N and M. Default scaling is 0 to 200 nanotesla. Non-default scaling to include infrequent extreme values is labeled in red to emphasize the change in scale. This page updates dynamically every 5 minutes.

7 Webpage: This electron flux plot contains the 5-minute averaged integral electron flux (electrons/cm2-s-sr) with energies greater than or equal to 0.8 MeV and greater than or equal to 2 MeV at GOES-13 (W75). These data are invalid during a significant proton event because of sensor contamination at the GOES spacecraft. Enhanced fluxes of electrons for an extended period of time have been associated with deep dielectric charging anomalies. Noon and midnight local time at the satellites are plotted as N and M.

11 About the Model Shown above is the latest forecast of conditions in the solar wind, as predicted by the WSA-Enlil model. The solar wind is a fast-moving stream of charged particles emanating from the Sun and moving outwards towards the Earth and planets. During fair-weather conditions the solar wind still contains significant variations in density and speed which originate at the solar surface and are imparted with a spiral appearance due to the Sun's roughly 27 day rotation. At irregular intervals the fair-weather is interrupted by major solar eruptions known as Coronal Mass Ejections (CMEs) which are propelled outwards into the background wind. Variations in the plasma density and speed within these solar storms can be much more dramatic than during quiet conditions. For both fairweather and storm conditions, predicting the arrival at Earth of variations in the solar wind is important because these can lead to geomagnetic storms. About the Plots The top row plots show predictions of the solar wind density. The bottom row plots show solar wind velocity. The circular plots on the left are a view from above the North Pole of the Sun and Earth, as if looking down from above. The Sun is the yellow dot in the center and the Earth is the green dot on the right. Also shown are the locations of the two STEREO satellites. These plots often depict spiral structures, due to solar rotation, as described above. The wedge-shaped plots in the center provide a side view, with north at the top and south at the bottom. The graphs on the right show the model predictions for the time evolution of density and velocity at the locations of Earth and of the two STEREO spacecraft. The yellow vertical line is in sync with the movies on the left, so it is possible to see how values of density and velocity correspond to particular solar wind structures. A model run mode for WSA-Enlil is indicated at the bottom: Ambient means that the model has been run in the quiet, fair-weather, mode while CME indicates a dynamic model run containing a prediction of one or multiple CMEs which may be directed towards Earth, or Geo-effective.
