An interesting paper has been published about “Evidence of Eta Aquariid Outbursts Recorded in the Classic Maya Hieroglyphic Script Using Orbital Integrations” by J.H. Kinsman and D.J. Asher. The history of Eta Aquariid outbursts has been reconstructed based upon a numerically integrated model of particles released from comet Halley. These calculated outbursts were matched with major events described in the Maya records. It is very likely that the Maya kept track of the Eta Aquariid activity associating outbursts with major events in their society.
