Solar Imaging – 1st March 2025

Equipment: Skywatcher 82ED / SGH700 Spectroheliograph

Camera: QHY678M

Solar Continuum – Surface Granulation & Sunspots

This image captures the Sun in the visible continuum, revealing surface granulation caused by convective plasma motions. Sunspots, which appear as darker regions, are areas of intense magnetic activity where the surface temperature is lower.

Dopplergram – Plasma Motion

This Doppler image maps the velocity of plasma on the solar surface. Blue areas indicate material moving toward us, while red areas show material receding. This technique helps study solar dynamics, such as oscillations and flares.

Negative Image – Enhanced Contrast

A negative version of the solar image helps enhance faint structures, making it easier to see filaments, prominences, and fine details in active regions.

Active Regions – Magnetic Activity

This image highlights active regions on the Sun, where strong magnetic fields emerge from the surface. These areas are often associated with sunspots, solar flares, and coronal mass ejections (CMEs).

Colorized Solar Image

A colorized version of the solar image enhances visibility and contrast of various features, making structures like sunspots, filaments, and bright faculae more distinguishable.

Doppler Eclipse – Velocity Mapping

This specialized Doppler image is processed to emphasize movement during an eclipse or limb transit, showing differences in solar rotation and plasma motion.
