New Meteor Shower Reports

The discoverer of a probable new shower is asked to propose a uniqe name to the Meteor Data Center (contact T.J. Jopek), following the shower nomenclature rules as closely as possible. The name should be unique and not create confusion with other showers in the list of all showers. If the discovery meets the standards of other such showers in the Working List, the shower will be added and assigned an IAU number and a three-letter code. The thee-letter code is an alternative and popular way to discriminate among showers because the code is easier to remember and recognize than numbers.

We accept all new showers about to be published in scientific journals. Please send a copy of the paper to the MDC before submitting the final version to the journal. The new name and number are to be used in that publication of the discovery and in subsequent discussions.

The International Meteor Organization (IMO) is assisting the MDC in this initial evaluation of 'probable' new streams. Streams accepted by the IMO should be reported in a paper in WGN, the Journal of the IMO, and the editor of WGN can contact the MDC to collect name and number.

In collaboration with the IAU Minor Planet Center, a CBET telegram will be issued periodically to indicate when new showers are added to the working list.

Before reporting to the MDC, amateur astronomers that recognize new meteor showers from visual and single-station video observations should contact the International Meteor Organization and present their claim for referral (point of contact: Juergen Rendtel). Observations should strongly suggest a shower. For example, an outbursts of a significant number of meteors from a compact radiant in a brief period of time (e.g., beta Hydrusids), or a persistent radiant detected in single-station observations over several nights, moving at the expected rate.

The goal of subsequent research is to establish the validity of the proposed shower and, if analysis confirms such validity, subsequently move the stream from the Working List to the List of Established Showers. Evidence that helps establish a shower in the Working List (or eliminate from the list) should be published in the literature, a copy of the paper should be provided to the MDC. Upon review of the evidence in the Working Group, the MDC will move that stream from the Working List to the List of Established Showers.

Each new shower in the List of Established Showers will receive its official name, and official recognition as being established, on recommendation to Commission 22 at the next IAU General Assembly.
