    Temporary Minor Planet Designations

    Temporary designations are assigned by observers prior to the assignment of provisional designations by the Minor Planet Center. With the rapid speed of e-mail communication, official provisional designations can be assigned very rapidly and there is no need for temporary designations to be publicised. In the past, when communication was slow, temporary designations were often published.

    There were a large number of temporary-designation schemes and to give full details on each of them would be a major undertaking. The notes below detail which schemes are included for the purposes of searching and give some examples of valid search strings.

    {LETTER} indicates capital letters (one or more, see examples
                    for which schemes allow both)
    {letter} indicates lowercase letters (one or more, see examples
                    for which schemes allow both)
    {year} indicates a year
    {number} indicates a number (one or more numbers)
    {greek} is a lower-case Greek letter (e.g., alpha or beta)
    {RN} is a Roman numeral (e.g., I or IX)
    For convenience some parts of certain designations are optional. Optional parts are indicated in brackets []. Other parts may be abbreviated as shown.
