In this book you will ﬁnd a description of suitable equipment for meteor photography, some sugges-tions and practical hints for photographic meteor observations and some guidelines for the analysis of successful meteor photographs. The four main topics covered are: (1) Photography of faint meteors in a small ﬁeld of view by common camera types A new version of the IAU MDC photographic meteor orbits database which is an upgrade of the current version (Lindblad et al. , EMP –) is presented. To the version additional orbits are added, thus the new version of the database consists of 4, meteors with their geophysical and orbital parameters compiled in 41 ://

Abstract. The new criterion D N for meteoroid stream identification, based on variables directly linked to observations, is applied to a set of photographic meteor orbits and the results are compared with those obtained using the well-known and widely used D S criterion of Southworth & Hawkins, using thresholds for meteor association computed according to Jopek & ://
The observed orbital dispersions of video Geminids, including the measurement errors, were and radar orbits of Geminids selected from the IAU Meteor Data Center [9, 10]. The semi-major axes of meteor orbits in almost all the video datasets seem to be systematically biased in comparison with the photographic and radar meteors. The Table 5.

In each station several photographic cam-eras or low-scan CCD detectors with 50 to 35 mm optics equipped with rotating shutters were installed. Camera oper-ators took time exposures with an accuracy of one second, while the time of occurrence of the bright meteors As of April 18 th, (last time the list below was updated), there are 33 meteorites with photographic orbits either published in a peer-reviewed journal or pre-published in a conference abstract volume or a thesis.

From Harvard photographic plates 36 meteors ( through6 double-station, 30 single- station) between November 15 G.C.T., have been analyzed. The mean radiant of the Leonid stream moves eastward along a great circle in Leo at a rate of 39' + 3' per day, and southward 25' + 3'.

The accuracy of photographic orbits is typically an or-der of magnitude better than those of radar orbits. Unlike radar orbits, photographic data potentially allow resolving the intrinsic scatter in the distribution of orbital elements.
The photographed meteors are typically in the size range of millimeter or centimeter size and larger &AS___pdf.
