Space weather refers to hazards to human’s and technology from the Sun, the solar wind and cosmic rays. One of the most important space weather events are extreme coronal mass ejections (CMEs) and solar flares which originate from active regions on the Sun. We implement data from the STEREO spacecraft, launched from Earth in 2006 and have since moved around the Sun with respect to the Earth to their current locations behind the Sun, to investigate what we can learn from having multi-point measurements of the solar wind for space weather forecasting. As there have been issues with the STEREO spacecraft, it is likely that in the future we are only likely to have in-situ and remote sensing data from the Earth and L1. We thus quantify the benefit to space weather forecasting and thus industry from having a spacecraft at L5. The spacecraft would be likely to be able to observe the Sun remotely to look for active regions rotating into view and also make in-situ measurements of the solar wind with the objective to predict CMEs and solar wind conditions from their observation before they rotate to Earth’s location.
