Observations from a 50 cm Ritchey-Chrétien Solar Telescope in São José dos Campos, Brazil:

The 50 cm RC solar telescope at these coordinates in São José dos Campos, generously funded by the Brazilian Space Agency and the Brazilian Ministry of Science, Technology, and Innovations,  is a instruemnt test workbench forthe GSST Mission. 

1. Location and Altitude: The RC solar telescope is strategically located at geographical coordinates 23.2198° S, 45.8916° W in São José dos Campos, a city in the southeast region of Brazil. 

2. Telescope Specifications: The observatory houses a 50 cm Ritchey-Chrétien (RC) solar telescope, funded by the Brazilian Space Agency  (AEB, grant number TED AEB 2020—20VB—PO 0009) and the Brazilian Ministry of Science, Technology, and Innovations (MCTI). This advanced optical design minimizes errors, providing high-quality images that are especially useful for precise solar observations.

3. Solar Photosphere Studies: The RC telescope is frequently utilized with a narrow-band filter with a central wavelength (CWL) of 630.16 nm ± 0.1 nm (@ 0˚ Angle of Incidence) and a Full Width at Half Maximum (FWHM) of ≤ 0.6 nm. This specification allows for focused study of the Sun's photosphere, including the estimation of the magnetic field at the solar photosphere.

4. Flux Reduction Techniques: To manage the intense solar radiation, the telescope employs a masks with circular holes, each with a diameter of 3 to 8 cm. This technique reduces the flux and helps to protect the telescope's sensitive detectors from potential damage.

5. Imaging: The 50 cm RC solar telescope captures high-resolution images and videos of the Sun, providing detailed visual data that aids scientists in understanding various solar phenomena such as solar flares, sunspots, and solar wind.

6. Data Collection and Distribution: The raw data collected by the telescope is shared with a working group for preliminary assessment, testing, and feedback. This step is crucial in refining the data processing techniques used.

7. Data Usage: Although the raw data is not recommended for scientific studies of solar activities at this time, it is a valuable resource for technical studies of image processing, including the development and testing of deep learning algorithms.

8. Public Outreach: The GSST/INPE/AEB team encourages the use of their images for non-commercial initiatives, public education, and information dissemination. They kindly request that all such usage properly acknowledges the source of the images or data.
