+    \item \textbf{Interpreting stray and scattered light in ComCam observations.} Approximately 20\% of ComCam pointings showed structured patterns of stray light along an edge and/or corner of the ComCam field of view, that are likely attributed to scattered light from bright stars located slightly outside the ComCam field of view.
+    Dedicated observations of bright stars were acquired to test the hypothesis that the structured scattered light arises from something related to the ComCam filters, rather than scattering from M2 baffles or another element that will be in place for LSSTCam.
+    There is currently no evidence for structured scattered light when the ComCam filters are removed.
+    \begin{itemize}
+        \item There remains a risk of structured stray light contamination arising from the M2 baffle.
+        The concern arises because the black coating on the M2 baffle is anodization rather than a more reflection-suppressing coating such as Aeroglaze.
+        There are ongoing modeling efforts and on-sky test planning to better understand the system, and potential stray light paths for LSSTCam.

+    \item \textbf{Contributions to delivered image quality}
     \begin{itemize}
         \item Understand discrepancies between AOS residual and delivered image quality
         \item Analysis of stuttered and guider mode imaging. Preliminary analysis of the stuttered and guide mode imaging data shows strongly correlated common mode motion between stars across the ComCam field of view, suggesting that the delivered image quality during those observations was dominated by dome and/or mirror seeing contributions, or telescope motion.
