New satellite data

The Japan Meteorological Agency recently launched a new geostationary weather satellite called Himawari-8. “Himawari” means sunflower, and the name has been given to a new series of satellites that we can look forward to in coming years. “Geostationary” means the satellite rotates “in sync” with the Earth, always above the same point over the equator. We, in New Zealand, are now starting to receive early data from this satellite.
