New User Sunrise Icon on Bluesky
'When you join Bluesky, there's a fun feature that marks your new-user status—a sunrise icon on your profile. This unique icon is a symbol that you are just starting out on Bluesky. It is a way to introduce new users while adding a bit of flair to your profile.
The sunrise icon is displayed prominently for the first few days of your membership, letting others know that you are a new member of the Bluesky community. You can find this icon on your profile, usually near your name or avatar. It includes a button and the SVG icon, making it easily recognizable and visually appealing.
What's special about this sunrise icon is that it is exclusive to new accounts. As your account ages and you become more familiar with the platform, the icon will eventually disappear.'
