SSC00-IV-3 Leonid Meteor Observer in LEO: A University Microsatellite to Observe a Meteor Shower From Space
This paper presents university-based design and development of a micro-satellite for the observation of a meteor shower from the low Earth orbit. The satellite will be launched as a piggy-back payload of a commercial rocket launcher, a few weeks before the 2001 or 2002 Leonid meteor maximum in which thousands of meteors are scientifically expected. The goal of the mission is to conduct the scie...
متن کاملSporadic-E associated with the Leonid meteor shower event of November 1998 over low and equatorial latitudes
Rapid radio soundings were made over Ahmedabad, a low latitude station during the period 16–20 November 1998 to study the sporadic-E layer associated with the Leonid shower activity using the KEL Aerospace digital ionosonde. Hourly ionograms for the period 11 November to 24 November were also examined during the years from 1994 to 1998. A distinct increase in sporadic-E layer occurrence is noti...
متن کاملLeonid meteor stream from Ondřejov radar observations in 1965 – 1967
Results of Ondřejov radar observations of Leonid meteor shower in 1965–1967 are presented. Observations performed during previous returns of Leonid meteor showers indicate that both in 1965 and 1966 the peak activity was observed at almost the same solar longitude near L = 235. ◦17. The activity pattern in 1965 showed two well pronounced peaks separated by 23 hours where the second one seemed t...
متن کاملAlpha Cygnids - a possible July minor meteor shower
We present a comprehensive study of a possible α-Cygnid meteor shower. Based on visual and telescopic observations made by Polish observers we estimate basic parameters of the stream. Activity of α-Cygnids lasts from around June 30 to July 31 with clear maximum near July 18 (solar longitude λ = 116.5◦). Maximal Zenithal Hourly Rates (ZHRs) are equal to 3.6± 1.2. The structure of the radiant ana...
متن کاملMAVEN IUVS observations of the aftermath of the Comet Siding Spring meteor shower on Mars
We report the detection of intense emission from magnesium and iron in Mars’ atmosphere caused by a meteor shower following Comet Siding Spring’s close encounter with Mars. The observations weremade with the Imaging Ultraviolet Spectrograph, a remote sensing instrument on the Mars Atmosphere and Volatile EvolutioN spacecraft orbiting Mars. Ionized magnesium caused the brightest emission from th...
