3. Feeds and tables

The published RSS/XML and JSON feeds and the tables contain object designations, magnitudes, observations, orbital elements, and derived working values from publicly available astronomical sources, especially the Minor Planet Center and local Find_Orb processing.

These astronomical data are not personal data of visitors to this website. Accessing feed and table files creates the same technical access data as a normal page request.

4. E-mail subscription and unsubscription

An e-mail subscription is created only when a registration mail is sent to the listed address. Stored data include the e-mail address, subscription status, time of the latest change, and, only for e-mail subscriptions, the requested station code and personal limiting magnitude. If omitted, station 500 and 20.0 mag are used.

Optional horizon profiles may reveal local obstructions or equipment settings. The profile is part of the recipient record; stored fields are the filename, detected format, SHA-256 checksums, and azimuth/altitude points normalized to north = 0° and east = 90°. Attachments are checked locally and used only for the requested visibility filtering.

A valid attachment activates or replaces the profile automatically. Horizon profile: none in a new registration mail removes it. Files that are not permitted or cannot be identified unambiguously as passive text profiles are not used and never overwrite an existing working profile.

• Purpose: delivery and filtering of MPC NEO Alert mails.
• Legal basis: Art. 6(1)(f) GDPR, legitimate interest in the requested notification; where the mailing is explicitly requested, additionally consent through the registration mail.
