In this composite view of the Sun, the image on the left, taken using a white light filter, provides a detailed look at the visible surface, or photosphere, revealing granular structures and sunspots that mark regions of complex magnetic activity. Sunspots are cooler areas created by strong magnetic fields inhibiting the transport of heat from the solar interior, appearing as dark blemishes on the solar surface.

On the right, the image captured with a Hydrogen-Alpha (Hα) filter unveils the chromosphere's dynamic features, showcasing solar prominences that tower over the Sun's limb. These prominences, composed of cooler plasma suspended in magnetic loops, offer a captivating glimpse into the intricate magnetic phenomena occurring on the solar surface.

Solar prominences can erupt in dramatic events known as solar flares, releasing intense bursts of energy and charged particles into space. These flares, often accompanied by coronal mass ejections (CMEs), can have significant impacts on our space environment, potentially affecting satellite operations and terrestrial communication systems.

Despite our common association of the moon with the nighttime sky, it is indeed possible to catch a glimpse of the moon during the daytime. While the sun's brilliance tends to overshadow the moon's subtle glow, certain conditions make it visible even in broad daylight. The moon's position in relation to the Earth and the sun plays a crucial role in its daytime visibility. When the moon is at or near its full phase, it rises in the east just as the sun sets in the west, allowing it to be visible for some time during the day. During this period, keen observers may spot the moon hanging delicately against the backdrop of the blue sky, lending an ethereal touch to the daytime experience.

Image Description and Details :

This morning, February 18, I photographed this magnificent prominence on the northeast limb of the sun. These two towers of hot plasma rise more than 90,000 km above the sun's surface.
On the solar disk, not many sunspots are seen but many filaments in multiple active regions are very noticeable.
To take this picture I used a Coronado Solarmax II 90mm telescope and a ZWO 183MM camera.
