Solar-Geophysical Data was a monthly bulletin issued from 1955 to 2009 in one or two parts that provides the scientific community with a variety of solar-terrestrial data. Solar-Geophysical Data was intended to keep researchers informed on a timely schedule of the major events on the sun and of their associated interplanetary, ionospheric, geomagnetic and cosmic ray effects. The report was made available through the cooperation of many observatories, laboratories and agencies whose data are summarized. Part I (Prompt Reports) contains data for 1 or 2 months before the month of publication, and some late data; Part II (Comprehensive Reports) contains data for 6 months prior to publication plus late and miscellaneous data.

The NOAA National Geophysical Data Center discontinued the publication of Solar-Geophysical Data reports in October of 2009.
