When is the best time to observe V336 Puppis?

V336 Puppis is best observed from December through February, with peak visibility during January when it transits around midnight in the Northern Hemisphere.

Where is V336 Puppis located in the sky?

V336 Puppis lies in the constellation Puppis at right ascension 08h 03m and declination -41° 19′.

What telescope do I need to split V336 Puppis?

Splitting V336 Puppis requires an aperture of roughly 60 mm or larger — the components are separated by about 26.5″ at magnitudes near 5.5. The companion is about 3.5 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.

Apparent motion is significant on a human timescale — worth revisiting in a decade.

Measured from the WDS observational archive. No orbital solution has been derived — most likely the period is too long to fit an orbit to the available measurement arc.
