Best time to see Mercury in Baltimore tonight
The best time to see Mercury in Baltimore tonight is, honestly, not tonight: Mercury is only above the horizon while the sky is still too bright for it, so it isn't realistically visible. Wait for a better apparition, when it stands higher in a darker twilight and its light can cut through.

Common questions
Where exactly should I look?
Nowhere useful tonight — Mercury is above the horizon only while the sky is still too bright for it from Baltimore, MD. Wait for a better apparition.
What's the exact best time?
There is no usable window tonight — Mercury is up only in bright twilight, too faint against the sky. Check back as its elongation from the Sun improves.
Do I need a telescope?
No, but binoculars help — Mercury hides in bright twilight near the horizon. Sweep with binoculars where the Sun set; a telescope adds little at that altitude.
Will clouds get in the way?
Tonight's cloud forecast is currently unavailable, so check the sky directly — bright planets show through all but solid overcast.
How bright is Mercury tonight?
Mercury shines at magnitude 3 tonight — on the fainter side, so darker skies help. Planets shine with a steady light while stars twinkle — that steadiness is the giveaway.
When is the best night to see Mercury this week in Baltimore?
Mercury has no usable night in this stretch — it is below the horizon after dark or lost in twilight every evening. Check back next week — the geometry shifts night to night.
