Provisional designations - Discoveries of station 881

The table contains all provisional designations from the corrected (alls IDs from dbl.txt and ids.txt are used) dataset UNNOBS of the Minor planet Center, for which the station 881 has made the discovery observations itself or has assigned a discovery star. Please be aware, that the designation must not be the discovery due to further identifications.

Explanations:
Nr: Running number.
Designation: Long designation of the object.
Short: Packed designation of the object.
Obs start: First date for this designation (may be not the first date for object due to prediscovery identifications).
Obs end: Last date for this designation (may be not the last date for object due to later identifications).
Int: Difference between last and first date in days.
Discovery: Date of discovery for this designation.
Sta: Discovery station.
Obs: Number of observations for this object.
Own: Number of own observations for this object.
Sta: Number of stations for this object.
Opp: Number of observed oppositions for this object.
Stars: Stations with discovery stars in all observations of this object. The 'real' discovery station is mostly the first one. Sometimes you must check the details of publication date and the sending date (which you may know, when you sent the data).
Reason: The reason of discovery. Rule is the MPC rule and star means the first asterisk in observations.
