Current Plot | One rotation back | Two rotations back || GFZ Rotation Plots
This plot is updated hourly.
The plot in the upper panel shows the provisional (quicklook) Kp index from GFZ Potsdam. The black curve is for the current solar rotation, and the green curve is for the previous rotation (27 days prior), and the red curve is Kp as predicted by the NOAA Space Weather Prediction Center.
The second panel is a plot of the total geomagnetic field strength as measured by a magnetometer on one of the NOAA GOES satellites. The vertical dashed lines indicate the times when the satellite is above the noon meridian (red) or above the midnight meridian (black). The black curves are for the dates shown along the X axis and the green curves are from an estimated quiet-day curve. These data were obtained from the real-time data available through the NOAA Space Weather Prediction Center.
The lower three panels are plots of data from the NASA Deep Space Climate Observatory (DSCOVR) satellite, from top to bottom: Bz and Bt, the z-component and total strength (gray curve) of the Interplanetary Magnetic Field (IMF); the number density of the solar-wind plasma; and the streaming velocity of the solar-wind plasma. As in the upper panel, the black curves are for the dates shown along the X axis and the green curves are from 27 days prior (the previous solar rotation). These data were obtained from the real-time data available through the NOAA Space Weather Prediction Center and older data from the NOAA National Centers for Environmental Information.
