A rare outburst of the annual Aurigid meteor shower was predicted to occur on 1st of September, 2007 [1]. Aurigid outbursts were, by chance, observed visually in the years 1935, 1986 and 1994. The model by Vaubaillon and Jenniskens [1] post predicted all these outbursts and, in addition, one in 2007. Very little scientific information was recorded during these past outbursts. The outburst in 2007 provided, for the first time, the opportunity to use modern instruments to gather a wide range of data products pertaining to the physical and dynamical properties of a longperiod comet and its constituent matter. Long-period comet C/1911N1 Kiess, discovered on July 1911, and observed only for 71 days, has a near-parabolic orbit and takes more than 2000 years to complete one revolution around the Sun. Only one outburst from a long period comet's dust trail has been observed by modern instruments [2]. These meteoroids whose parent object is still unknown were found to be low in volatile elements such as sodium, compared to meteoroids from short period comets. One possible hypothesis is that because of the infrequent visits of long period comets to the inner solar system, the meteoroids ejected from these comets could be from the pristine crust, possibly exposed to cosmic rays in the Oort cloud. Thus, Aurigid meteoroids detected in 2007 could reveal fundamental properties of long period comets and their surroundings.
