There are two accounts with which you have to work during your stay at the Observatory:

• STRW account
• ULCN account

This account is used for al your daily activity when using the STRW/Observatory computing facilities. So your Observatory mail and computer login are associated with this mail account. It is the account in which yo save all your scientific data/software etc.

With your STRW account an email address and box is associated. You can access that box in several ways, see Getting started with your STRW email

For most administrative purposes, such as recording days off, travel declaration and yearly Performance and Development Interview you have to use the ULCN account.

The ULCN account is an account provided to you by the University to allow you to login to all centralized facilities, such as SAP Self Service for all your centralized administrative duties.
