Fall RCN Meeting -- October 20th, 2022

The first full RCN meeting will take on October 20th, 2022 from 8a - 12p Pacific (11a-3p Eastern, 4p-8p UK, and 5p-9p CEST) via Zoom (link here).

If you are planning to attend, please take a moment and fill out this RSVP form to assist in planning efforts for our networking / breakout rooms.

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
