Vinz Franktake a look at the impressive sunspot AR3664! I took this photo last year :) These fascinating structures on the solar surface demonstrate the dynamic nature of our sun. Sunspots are not only beautiful to look at, but also important indicators of solar activity.☀️🔭<br> <br> <a href="https://pixelfed.social/discover/tags/Sunspot?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Sunspot</a> <a href="https://pixelfed.social/discover/tags/AR3664?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#AR3664</a> <a href="https://pixelfed.social/discover/tags/Astronomy?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Astronomy</a> <a href="https://pixelfed.social/discover/tags/Sun?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Sun</a> <a href="https://pixelfed.social/discover/tags/Space?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Space</a> <a href="https://pixelfed.social/discover/tags/SolarActivity?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#SolarActivity</a> <a href="https://pixelfed.social/discover/tags/Astrophotography?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Astrophotography</a> <a href="https://pixelfed.social/discover/tags/SpaceLovers?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#SpaceLovers</a> <a href="https://pixelfed.social/discover/tags/Nature?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Nature</a> <a href="https://pixelfed.social/discover/tags/Science?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Science</a> <a href="https://pixelfed.social/discover/tags/AstronomyLovers?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#AstronomyLovers</a>
