We were warned that this weekend’s solar storm could have an impact on GPS and navigation systems. 404 Media reports that it’s causing outages in the GPS and real-time kinematic (RTK) positioning systems used in many farmers’ tractors, right in the middle of planting. This is a bigger problem than you might think: quite a lot of crops are grown using precision agriculture, “with farmers using increasingly automated tractors to plant crops in perfectly straight lines with uniform spacing. […] If the planting or harvesting is even slightly off, the tractors or harvesters could damage crops or plant crooked or inconsistently, which can cause problems during the growing season and ultimately reduce yield.” To say nothing of the harvest. Precision agriculture achieves centimetre-level accuracy, but also relies on it, and losing it at one step of the process can’t be good. [Engadget, The Verge]

G5-Scale Geomagnetic Storm in Progress
The Earth is being hit by a solar storm at the moment; NOAA’s Space Weather Prediction Center (SWPC) has observed severe (G5) geomagnetic storm conditions for the first time since 2003. Among other impacts, this may disrupt GPS and other navigation systems. On the other hand this also means aurorae where they’re rarely seen: see SWPC’s aurora dashboard for maps.
