Planet Combustion
Annual five-planet combustion intervals under a named threshold convention.
Five-planet longitude-threshold model: Mars 17°, Jupiter 11°, Saturn 15°; Venus 10° direct / 8° retrograde; Mercury 14° direct / 12° retrograde. These thresholds follow Surya Siddhanta 9.6–9 as reproduced in Visti Larsen’s study. This is a traditional longitude classification, not an atmospheric visibility forecast. Moon and nodes are outside this model.
