When is the best time to observe HIP 19284?

HIP 19284 is best observed from October through December, with peak visibility during November when it transits around midnight in the Northern Hemisphere.

Where is HIP 19284 located in the sky?

HIP 19284 lies in the constellation Taurus at right ascension 04h 08m and declination +17° 20′.

What telescope do I need to split HIP 19284?

Splitting HIP 19284 requires an aperture of roughly 100 mm or larger — the components are separated by about 4.8″ at magnitudes near 5.9. The companion is about 3.8 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
