Summary[edit]
| Description |
English: Comet 12P/Pons–Brooks
12P/Pons–Brooks is a Halley-type periodic comet with an orbital period of 71 years. It was discovered in 1812 and later recovered during passages in 1883 and 1954. It is expected to brighten to an apparent magnitude of 4.5 (visible to the naked eye) during its upcoming passage in April 2024. This image shows the comet during a recent outburst, releasing billions of pounds of gas and dust while brightening to an apparent magnitude of 8.8 (about 60x brighter than the predicted magnitude of 13.2). Note how the inner coma surrounding the core is much brighter than the faint outer coma. Apparent magnitude: 8.8 Distance from Earth: 2.72 AU Orbital period: 71 years Velocity (relative to Sun): 41.0 mile/s (25.5 km/s) Total integration: 52 minutes 26 x 120 seconds (Gain 0, Offset 50, Temperature -5 C) 11/18/2023 23:05 to 00:07 UTC Camera: ZWO ASI2600MC Pro Telescope: Explore Scientific ED80 f/6.0 Apochromatic Refractor (with HoTech 2" SCA Field Flattener) Mount: Orion Sirius EQ-G Guide scope: Svbony 50mm f/4.0 Guide Scope Guide camera: ZWO ASI224MC Capture software: N.I.N.A., ASTAP, PHD2 Bortle Class 6 ~19.32 mag/arcsec^2 (Summerville/Ladson, SC) Processed with PixInsight and GIMP |
