• VLASS News:

1. SSG meeting schedule and co-chair
   • • Next meeting will be on May 22 (same time, same link)
     • Co-chair/back-up chair needed to cover my absence while on maternity leave, starting sometime in July (volunteers?)
     • Observing and data processing status – Amy Kimball, Mark Lacy

• No new observing to report
  • Data processing:
    • currently finishing up B-config 3.1 QL, BnA starts May 30th
    • SE processing awaiting new personnel training (current forecast is to resume this in late summer 2023)
  • Automated QA developments for QL that are expected to be adaptable for SE imaging
    • NOTE: good topic for future SSG talk
  • Changes to BnA scheduling were discussed
    • Phase referencing cycle time has been reduced to conform to current NRAO guidelines (now as short as 11-12 minutes for S-band/B-config)
    • NOTE: Commensal instruments have requested that NRAO give them a heads-up about future observing strategy strategies

1. Events
   • Splinter session update for AAS #242 (June 2023) – Steve Myers
     • Preliminary schedule
       • Suggestion: Jupyter notebooks on splinter session webpage?
     • Action item: Brian Kent and Steve Myers will make VLASS/splinter session flyer(s) and share with SSG at next meeting, and will also follow-up on advertising session on social media (an organizer has to do this; NRAO EPO will not post science community content to social media)
     • Action item: Let Steve Myers know if/when you are giving a VLASS-related talk scheduled for a different session
     • Other conferences?
