Recover requesting log seq#1

What could be the reason for an recover to request archvied log seq#1? The database files, redo logs, rollback segments were copied from a clean (normal) shutdown database at log seq# 25. Backup controlfile was created immediately before the shutdown.

alter database recover managed standby database Media Recovery Start: Managed Standby Recovery Starting datafile 1 recovery in thread 1 sequence 25 Datafile 1: 'C:\ORACLE\ORADATA\BLAUDB\SYSTEM01.DBF' Starting datafile 2 recovery in thread 1 sequence 25 Datafile 2: 'C:\ORACLE\ORADATA\BLAUDB\UNDOTBS01.DBF' Starting datafile 3 recovery in thread 1 sequence 25 Datafile 3: 'C:\ORACLE\ORADATA\BLAUDB\CWMLITE01.DBF' Starting datafile 4 recovery in thread 1 sequence 25 Datafile 4: 'C:\ORACLE\ORADATA\BLAUDB\DRSYS01.DBF' Starting datafile 5 recovery in thread 1 sequence 25 Datafile 5: 'C:\ORACLE\ORADATA\BLAUDB\EXAMPLE01.DBF' Starting datafile 6 recovery in thread 1 sequence 25 Datafile 6: 'C:\ORACLE\ORADATA\BLAUDB\INDX01.DBF' Starting datafile 7 recovery in thread 1 sequence 25 Datafile 7: 'C:\ORACLE\ORADATA\BLAUDB\ODM01.DBF' Starting datafile 8 recovery in thread 1 sequence 25 Datafile 8: 'C:\ORACLE\ORADATA\BLAUDB\TOOLS01.DBF' Starting datafile 9 recovery in thread 1 sequence 25 Datafile 9: 'C:\ORACLE\ORADATA\BLAUDB\USERS01.DBF' Starting datafile 10 recovery in thread 1 sequence 25 <-- looks fine Datafile 10: 'C:\ORACLE\ORADATA\BLAUDB\XDB01.DBF' Media Recovery Log
