A new interstellar comet has just been discovered, 3I/ATLAS. I have added it to the July current comets list for all versions of SkyTools. It is currently magnitude 18.5.
Clear skies,

Thanks Greg.
ST4 predicts it'll be visible in November 2025, but we have garbage weather then.

Its too soon to say what its visibility will be, Phil. Its a comet, its still far from the sun and could "turn on", we don't have a long history of observations to build on, and its interstellar in origin. So hang on.
Clear skies,
