   • Other topics?
4. VLASS Epoch 4
   • • Science pitch write-up (Mark Lacy): here
     • Overleaf draft of SSG's white paper on VLASS Epoch 4 - Kristina Nyland
     • White paper plan: have working group chairs lead and organize input on their respective topics
       • Chenoa and Joe Lazio working on making more quantitative arguments for fast transients/SETI, looking at Ep 3 data.
       • Any SSG member should feel free to invite people to contribute to the case.
     • Community freedback solicitation:
       
       1. NRAO eNews article sent Sept 7th
       2. Summer AAS VLASS presentations
       3. Other ideas:
          • Social media (LinkedIn, Facebook, Twitter, etc. - individual SSG members would need to spearhead this; NRAO EPO does not solicit science content on social media)
          • Zoom webinar on new VLASS opportunities?

• • Proposal details and timeline
    
    • Kristina will write-out a formal timeline for completing the proposal.
    • Kristina will set-up a poll for one or more working group chair meetings starting in late October. Working group chairs will be asked to solicit input from other members of the SSG/broader community and compose scientific summaries of the opportunities/impact of a 4th epoch of VLASS.
    • Kristina will re-organize the current draft so that it's better suited for contributions from the working group chairs.
• SE Image prioritization

• SSG/community interest in this?
• Input on request form?
• Chenoa had feedback requesting prioritization of overlap with existing surveys.
• Joe has a list of radio stars, sent to Steve and Mark.
• ML priortizing Stripe 82 (one of Joe's stars in that); North Ecliptic Cap, any other favorites?

• Future meetings: (subject to change; check your email/Slack for updates)

• • Kristina will poll (see above)
