  "abstract": "We present and study supersymmetric warped ${\\rm AdS}_2 \\times {\\rm M}_7 \\times I$ solutions of Type IIA supergravity, where M$_7$ is a weak G$_2$ holonomy manifold. Locally, the solutions are characterized by a cubic polynomial. We distinguish two branches, Branch 1 and Branch 2, and analyze their global properties, taking flux quantization into account. At the endpoints of the interval $I$ they exhibit either OF1-plane or O8/D8 type of singularities with Branch 1 allowing also for a Spin(7) cone. In the case of zero Romans mass, Branch 1 uplifts to eleven dimensions to ${\\rm AdS}_4 \\times {\\rm M}_7$ whereas Branch 2 uplifts to warped ${\\rm AdS}_3 \\times {\\rm M}_7 \\times I$ with OM2-plane type of singularities.",
