Solar Geophysical Data (SGD) Reports (1955-2009)
Solar-Geophysical Data (SGD) reports were a comprehensive compilation of many different
kinds of observational data of the sun's activity and its effects on the Earth. Data
from the worldwide network of geophysical and solar observatories were compiled each
month. The data began to be complied in November 1955 and ended in September 2009.
SGD helped keep researchers informed of the major events on the sun and associated
interplanetary, ionospheric, radio propagation and other geophysical effects. This
report series was made possible through the cooperation of many observatories, laboratories
and agencies worldwide. Data included: daily maps of the sun showing active regions,
daily sunspot information, event data such as solar radio and flare events, satellite
data such as solar wind and interplanetary magnetic field measurements, cosmic ray
data, geomagnetic activity data, and ionospheric propagation indices. The SGD was
divided into two reports, the Prompt Report contained data available for one and two
months before the report publication date and the Comprehensive Report that contained
data that became available six months after the report publication date.

Supplemental Information |
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.

Purpose | The Solar Geophysical Data (SGD) reports provided the scientific community with a comprehensive historical record of solar and geophyscial phenomena. |
