Please note: SDO entered a safe hold during a lunar transit at approximately 11:30 UT on August 2, 2016. All instruments were powered off. HMI resumed taking data at 00:55 UT on August 4, 2016. The flight software was successfully loaded onto AIA on Aug 9th. Images for all AIA channels are being taken since the sequencer was started at 2016-08-09T22:15. The instrument team still needs time to check the data processing pipeline and the scientific quality of the data. Calibrations will need to be run in the coming days. Before such measures have been performed, we caution the use of recent AIA data for scientific purposes. Also note that HMI data has intervals of poorer than normal pointing when SDO was not in "Science Mode", check the QUALITY keyword before assuming the data is normal.
Welcome to the Joint Science Operations Center (JSOC) Science Data Processing (SDP) home. Data products from the Solar Dynamics Observatory, as well as certain other missions and instruments, are available from the JSOC database. The following instruments and projects have data archived here:
Helioseismic and Magnetic Imager (HMI): is one of three instruments aboard the Solar Dynamics Observatory(SDO) designed to study oscillations and the magnetic field at the solar surface. HMI observes the full solar disk at 6173 Å with a resolution of 1 arc second and is a successor to the Michelson Doppler Imager(MDI) on the Solar and Heliospheric Observatory(SOHO).
Atmospheric Imaging Assembly (AIA): is another instrument board the Solar Dynamics Observatory(SDO) designed to study the solar corona, taking simultaneous full disc images in multiple wavelengths of the corona and transitional region (up to half a solar radius above the solar limb), with 1.5 arc sec resolution and 12 second temporal cadence or better. The primary goal of the AIA Science Investigation is to significantly improve our understanding of the physics behind the activity displayed by the Sun's atmosphere, which drives space weather in the heliosphere and in planetary environments.
Michelson Doppler Imager (MDI): is the predecessor to the current HMI and was launched aboard the Solar and Heliospheric Observatory (SOHO). It is a project of the Stanford-Lockheed Institute for Space Research and part of an international collaboration to study the interior structure and dynamics of the Sun. All the data observed by MDI is now archived in the JSOC.
Stanford Helioseismology Archive (SHA): is a compilation of helioseismology data from various missions including Global Oscillations Network Group (GONG), Mount Wilson, Magneto-Optic Two-Height Instrument (MOTH), Taiwan Oscillations Network (TON) and others to facilitate research.
Interface Region Imaging Spectrograph (IRIS): is a multi-channel imaging spectrograph with a 20 cm UV telescope which will obtain UV spectra and images with high resolution in space (0.33-0.4 arc sec) and time (1s) focused on the chromosphere and transition region of the Sun. The primary goal of the IRIS explorer is to understand how the solar atmosphere is energized.
Sudden Ionosphere Disturbance(SID) Monitors program is an educational project to build and distribute inexpensive ionospheric monitors to students around the world.These monitors detect solar flares and other ionospheric disturbances. JSOC is the central data repository where students can exchange and compare data.
