#astronomy Prepare for brilliant CometATLAS (C/2019Y4) within the northern spring sky! Astronomy Now4/2/2020
Northern Hemisphere skywatchers are getting enthusiastic about Comet C/2019 Y4, found at Mauna Loa in Hawaii on 28 December 2019 by the Asteroid Terrestrial-impact Final Alert System (ATLAS) when it lay among the many stars of Ursa Main. Now designated Comet ATLAS (C/2019 Y4), astronomers quickly famous that its orbit is similar to C/1844 Y1, the celebrated ‘Nice Comet’ of 1844. If Comet ATLAS is a fraction of C/1844 Y1, we may very well be in for a deal with. At the moment (2 April) shining with a greenish glow round magnitude +7.5 and traversing the considerably obscure northern constellation of Camelopardalis (the Giraffe) at a fee of about two-thirds of a level per day, C/2019 Y4 has brightened 6000-fold within the final two months. If it continues on the predicted fee, the comet may very well be a naked-eye object from rural places across the time of latest Moon on 23 April.
At 0h UT (1am BST) on 2 and three Might, Comet ATLAS lies 1½ levels southeast of fourth-magnitude star beta (β) Camelopardalis, which regardless of its Bayer designation is definitely the brightest star within the constellation. On 12 Might, C/2019 Y4 crosses the constellation border into Perseus. Presently it may very well be the third magnitude and transferring relative to the celebs at a fee of a level (or twice the width of a full Moon) per day. At nautical nightfall on Saturday, 16 Might (round 11pm BST within the coronary heart of the UK), the probably second-magnitude comet lies simply 12 arcminutes, or one-fifth of a level from magnitude +four.1 star mu (μ) Persei, however the pair can be simply 18 levels excessive within the north-northwest. New Moon happens on 22 Might. Comet ATLAS passes closest to Earth at 10h UT (11am BST) on Saturday, 23 Might at a distance of zero.781 astronomical models, or 117 million kilometres, traversing the constellation of Perseus at a fee of two levels per day. C/2019 Y4 stays circumpolar for an observer within the coronary heart of the British Isles up till about 24 Might. Thereafter, UK observers might want to search for it in a quickly brightening sky across the onset of civil twilight about 4am BST, some 50 minutes earlier than dawn. If it brightens in accordance with predictions, the comet ought to have a complete magnitude much like Venus and situated very low within the northeast in brilliant twilight. C/2019 Y4 passes into the constellation of Taurus on 26 Might and two days later a mix of distance and beneficial viewing geometry signifies that it attains a peak fee of movement with respect to the celebs of 2½ levels per day.
