When is the best time to observe HIP 41515?

HIP 41515 is best observed from December through February, with peak visibility during January when it transits around midnight in the Northern Hemisphere.

Where is HIP 41515 located in the sky?

HIP 41515 lies in the constellation Pyxis at right ascension 08h 28m and declination -35° 07′.

What telescope do I need to split HIP 41515?

Splitting HIP 41515 requires an aperture of roughly 60 mm or larger — the components are separated by about 25.1″ at magnitudes near 5.8. The companion is about 3.9 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.
