Hello All,

Hello All,

This is Evan, part of the YSO NSV 24045 (HD 163296) observing program. If you have any questions about the program please feel free to ask!

I wanted to let you guys know that the Hubble Space Telescope observations now have firm dates: night of April 14-15 and July 18th. We have scheduled near-IR observations to be as contemporaneous with the HST observations as possible: April 5-6th, and April 15th and 16th. Since changes in brightness is larger than a day, any optical photometry you are willing to provide does not need to be exactly contemporaneous (eg. within a day) with the near-IR and Hubble Space Telescope observations.

Good observing and clear skies!
