我们描述了詹姆斯·韦伯太空望远镜（JWST）黄道北极（NEP）时域场（TDF）的选择，这是一个直径为14 '的场，位于JWST的北方连续观察区（CVZ）内，中心位于（RA），decl.）J2000 =（17：22：47.896，+65：49：21.54）.我们证明，这是天空中JWST可以观察到干净（即，没有明亮的前景恒星和低银河前景消光）在任意节奏或任意方向的这种大小的河外深巡天，并且没有在升高的黄道背景方面的惩罚。这将至关重要地实现广泛的新的和令人兴奋的时域科学，包括高红移瞬态搜索和监测（例如，SNe），从活动星系核（AGN）到褐矮星大气的变率研究，以及可能极端分散的柯伊伯带和内奥尔特云天体以及附近银河系褐矮星、低质量恒星和超冷白色矮星的自行。JWST/NIRCam+NIRISS GTO程序将提供初始0.8-5.0 μm分光光度表征，以在该视场内的四个正交“轮辐”的m AB = 28.8 ± 0.3等。该领域的多波长（通过X射线的无线电）背景已经掌握（地基近紫外-可见-近红外），正在进行（VLA 3 GHz，VLBA 5 GHz，HST紫外可见，钱德拉X射线和IRAM 30 m 1.3和2 mm）或计划（JCMT 850 μm）。我们欢迎并鼓励对GTO的初步观测和辅助数据进行地面和空间跟踪，以实现其作为理想的JWST时域社区场的潜力。

We describe the selection of the James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF), a ≳14′ diameter field located within JWST’s northern continuous viewing zone (CVZ) and centered at (R.A., decl.)J2000 = (17:22:47.896, +65:49:21.54). We demonstrate that this is the only region in the sky where JWST can observe a clean (i.e., free of bright foreground stars and with low Galactic foreground extinction) extragalactic deep survey field of this size at arbitrary cadence or at arbitrary orientation, and without a penalty in terms of a raised zodiacal background. This will crucially enable a wide range of new and exciting time-domain science, including high-redshift transient searches and monitoring (e.g., SNe), variability studies from active galactic nuclei (AGNs) to brown dwarf atmospheres, as well as proper motions of possibly extreme scattered Kuiper Belt and Inner Oort Cloud Objects, and of nearby Galactic brown dwarfs, low-mass stars, and ultracool white dwarfs. A JWST/NIRCam+NIRISS GTO program will provide an initial 0.8–5.0 μm spectrophotometric characterization to m AB ∼ 28.8 ± 0.3 mag of four orthogonal “spokes” within this field. The multi-wavelength (radio through X-ray) context of the field is in hand (ground-based near–UV-visible–near-IR), in progress (VLA 3 GHz, VLBA 5 GHz, HST UV-visible, Chandra X-ray, and IRAM 30 m 1.3 and 2 mm), or scheduled (JCMT 850 μm). We welcome and encourage ground- and space-based follow-up of the initial GTO observations and ancillary data, to realize its potential as an ideal JWST time-domain community field.
