#26. Spot the Asteroid
Here are this week's 3 links worth exploring:

HelioLinc3D is a new program developed by researchers at the University of Washington to discover Near Earth Objects (NEO). Searching through a NEO data set, it has already made its first discovery: a "potentially hazardous" 180 metre asteroid designated 2022 SF289 that passes within 225,000 kilometres of Earth orbit, and that older surveys had missed. Requiring half the number of images that conventional survey algorithms would use, HelioLinc3D combined fragments of data spread across four nights of observations to make the discovery: https://www.washington.edu/news/2023/07/31/heliolinc3d/

A discovery of a NEO is made when a point of light is observed in a series of night sky images moving unambiguously in a straight line. Collecting the necessary evidence can be stymied by poor weather, extreme faintness of the object, or hidden in the background glare of brighter stars. HelioLinc3D was specifically designed for the Vera C. Rubin Observatory and its 10-year survey of the sky to begin in 2025, and the program's C++ implementation is open source and available on GitHub: https://github.com/lsst-dm/heliolinc2

Montage is an open-source toolkit developed at Caltech for assembling astronomical images into custom mosaics. Runs on Linux/Unix platforms and preserves spatial and calibration fidelity of input images. It supports all projections and coordinate systems in use in astronomy: http://montage.ipac.caltech.edu/
