@whybird@aus.social What? I lived in Adelaide for a year and nobody showed me the bunny!? I see the man a bit differently, with big sad eyes, a big nose and an open mouth. His right cheek is flushed and age spots are visible near his left eye! I hope this helps 😂

@whybird@aus.social @Jaffa@social.linux.pizza @astro_jcm@mastodon.online It's not only the sun, in Adelaide the moon is upside-down🙃 and the first quarter comes last! Most confusing for a Canadian. (Image from https://curious.science.org.au/everything-else/calendars)

@AstroHyde @AllanICarswellObservatory Unfortunately too many clouds... We'll have to wait for Artemis IV😲

@AstroHyde @AllanICarswellObservatory Thanks, there's a chance to photograph it with a small telescope! (As long as the clouds go away)
