The Opticon RadioNet Pilot (ORP) launches the Multi-Facility Call for Proposals and invites astronomers from diverse fields to submit observation proposals using multiple observatories for the same scientific project. Assistance is available to support the submission of multi-wavelength proposals. This initiative aligns with ORP's commitment to advance collaborative and cutting-edge astronomical research.

Key details of the call: 

- Participants have the chance to access more than eighteen individual facilities, expanding the scope of their research.  

- There are no restrictions on the scientific areas that can be proposed, fostering a diverse range of research avenues.

- Observation programmes must involve a minimum of two ORP facilities, encouraging collaboration and maximising the potential for impactful discoveries.

- The call is applicable to both non-simultaneous (non-time-critical) and time-critical/sensitive observations (e.g. contemporary or with the requested cadence). 

Submission Deadline: Interested researchers are urged to submit their proposals by the 9th of April 2024 at 14:00 UTC/15:00 BST/16:00 CEST. For detailed information on the call and guidance on submitting proposals, please visit the official ORP website at https://www.orp-h2020.eu/ORP-multi-facility-call.
