EPRV 5 Coworking Day
March 31st, 2023
The RCN is planning to host a collaborative workspace the day after the EPRV 5 conference wraps up (Friday, March 31st) at the same hotel. Conference attendees are invited to take advantage of having so many EPRV community members in the same place and to use this space at the hotel to work with new or existing collaborators on new science ideas, proposals, group tag ups, etc. If you are interested in attending, please take ~1 minute to fill out this Google Form and let us know what kind of structure would be most useful / of interest to you.
Fall RCN Meeting
October 20th, 2022
A full recording of the seminar is available on the RCN Google Drive
Note: visit the Pyaneti wiki for instructions on how to install Pyaneti ahead of the meeting OR visit this Pyaneti wiki subpage for instructions on how to run the package from a Virtual Machine environment if you want to skip the local install process.
Both options should allow full participation in Oscar’s tutorial!

Extreme Precision RV Foundational Science Seminar
April 26th, 2022
This seminar featured the PIs from NASA’s 2021 ROSES call on ‘EPRV Foundation Science’ which focused on new pathways to mitigating stellar variability in (E)PRV data. Each speaker described the scope of their project and provided updates on their teams progress in the first year+ of effort. You will find more details below, including the program schedule, presentation abstracts, and connection information.
A full recording of the seminar is available on the RCN Google Drive
