| A summary figure of THEMIS level 1 [[observation:data | data products]]. These are the datasets that are directly generated during an observation with THEMIS. The full Sun and slitjaw images are context images that are mainly used to have basic information of the solar condition on the Sun and the location of the high resolution observations. They are not really meant for scientific use, as equivalent data of a better quality can be obtained by other instruments. The main scientific data are the [[observation:data#Broadband images (BBI)| broadband images]] to study the dynamics of the solar photosphere at high-cadence and high spatial resolution, and the [[observation:data#Spectral images]] from which physical properties such as composition, density, temperature, velocities and magnetic field of the emitting solar plasma can be derived. | |
| | Thirty years ago, in March 1996, THEMIS witnessed its first light. For the first time, THEMIS targeted and tracked the Sun (upper right image of THEMIS tracking software, still in used today). THEMIS long-slit spectrograph acquired its first solar spectral images (bottom right image). This key moment was a pivotal point marking the transition of the end of the development of the project toward the start of its scientific exploitation. It crowned a twenty year effort, which started in the middle of the 1970's, for the construction of what is still the largest French solar telescope, and one of the world-largest one. The construction and design of the THEMIS telescope was led by J. Rayrole (picture on the left taken for the 1st light) along with P. Mein and M. Semel, the three "founding fathers" of THEMIS. |
