The Mayas and Eta Aquariids in AD 250-909

From the meteor library 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. The complete article can be consulted online:...

A meteor stream study of 1966

by Alexandra Terentjeva (Institute of Astronomy of the Russian Academy of Sciences, Moscow, Russia): ater@inasan.ru 3600 individual photographic orbits of meteor bodies and about 2000 visual meteor radiants with corresponding velocities were compiled and carefully studied in detail. 154 minor meteor streams were detected in the Solar System, their basic orbital and other data are given. Firstly some remarkable shower and stream properties are established: examples of the large elliptic radiation areas with semi-major axes perpendicular to the Ecliptic; the existence of the Northern (N) , Southern (S) and Ecliptical (Q) branches of some streams; stream-antipodes and radiant-antipodes (symmetrically arranged relatively to the Ecliptic) with angular distances from the Ecliptic to 40-80°; а number of short-perihelion streams (q ~ 0.05-0.07 A.U.); some meteor streams perpendicular to  the Ecliptic’s plane. There are also some unique meteor bodies with their orbits enclosed within the limits of the Earth’s one, or having the clockwise and anticlockwise direction in two similar orbits. Hyperbolic photographic velocities  vh = 57-88  km /sec  are treated as real ones according to the best radar and visual observations. А «bunch» of ecliptical streams, discovered in the USSR in 1950, is а complex of orbits of the mostly massive meteor particles of the Zodiacal Cloud.  The stream evolution rate is comparatively high. The total complex of sporadic meteor bodies is not totally chaotic and accidental. Introduction This work published...

“Who writes, who remains” One of the major problems with amateur meteor work is that a lot of all observing efforts that have been done past two centuries have been lost forever because nobody bothered to publish these results or to archive publications. What we know today about amateur meteor work in the 19th and 20th century is what has been published in the past by dedicated amateurs. Long time ago meteor observing reports were systematically published in professional scientific journals such as the Monthly Notices of the RAS, the reports of the British Association for the Advancement of...
