The position of the photocenter of LHS 1070 with respect to a Tycho catalog star. The pre-flare position was obtained using the 101 images before the flare. Its uncertainty can be estimated from the bidimensional distribution of individual positions, and results in a positional accuracy of  ~20 mas. The six images around the peak of the event define the position of the photocenter during the flare. The predicted positions of ℬ and components are marked with an “ × ” symbol considering component at the origin. The box shown in the upper right corner represents the size of one pixel.
