Novato Meteorite Consortium

Novato N01 was donated by Lisa Webber and Glenn Rivera to enable analysis by Novato Meteorite Consortium members. Please consider donating a small part of your future find to research so we can sample as many different parts of the asteroid as possible.

The following research teams (team lead given) are participating in a Novato meteorite consortium established to coordinate the analysis of the Novato meteorite samples and encourage as many samples to be studied as possible.

How to preserve your meteorite finds

To keep your meteorite in the best possible shape, here are some general guidelines:
  • Keep magnets away from them (in order not to destroy any natural magnetism in the rock)
  • Do not touch the meteorites (in case your hands contain moisture, oils, and bacteria).
  • Use aluminum foil to collect the meteorite and to store and handle it.
  • When you show the meteorites to others, minimize exposure to moisture (such as from people talking over it).
  • Keep plastics away from the meteorite. No storing in plastic bags, plastic containers, no touching with gloves.
  • Store the meteorites wrapped in aluminum foil in a clean (no smell) glas jar, covered by a sheet of aluminum foil. Put that jar in a bigger jar with closed lid with some desiccant on the bottom (if no other desiccant is available, one-minute rice will do). Allow the meteorite to dry out in this way to remove all adsorbed water vapor.
Please check also other sources of information to make sure you are doing your utmost best preserving the meteorite against weathering.

Background

Report your find: This website, maintained by Dr. Jenniskens, keeps an official tally of the recovered meteorites. Each recovered meteorite is given a number. By knowing the location of the meteorite in the strewn field, it is possible to relate the properties of the meteorites back to a position in the original asteroid. By using the numbers in publications and trade, thus keeping track of the find location, over time we will get a glimpse of the fascinating little world that collided with Earth.

Unique aspects of Novato: The fireball crossed the cameras of the CAMS meteor shower surveillance project in the San Francisco Bay Area. CAMS provides an accurate trajectory and orbit in space. The calculated path over Novato was published in the SF Chronicle, which led Lisa Webber on the following Saturday to check her yard for the cause of impact sounds heard on the roof that evening. This first find made it clear what to look for. The recovered meteorites typically have lost much of their fusion crust and are not easily differentiated from some weathered terrestrial rocks.
