The combination of extinction and scattering (i.e., attenuation) due to dust grains remain a critical uncertainty; for nearly all astronomical measurements, one needs to account for the dust in space. A technique to obtain extra-galactic spatially resolved attenuation measurements is to use partially overlapping -occulting- galaxy pairs: an astrophysical experiment in the optical properties of the interstellar medium that models the light of both galaxies and infers the missing light in the regions of overlap. In this talk, I present attenuation, reddening slope (RV) and color excess ratio (Eλ-V/EB-V) measurements mapped pixel-by-pixel from optical to near infrared wavelengths within the overlap of geometrically ideal occulting galaxy pair VV191. I will discuss what we learn about the dust properties of this galaxy pair and show that attenuation inferred from the Balmer decrement is twice that of the total average attenuation through the disk, decreasing with galactic radius.

Blackacre was thrilled to host a Harvest Moon Hike in partnership with LAS in September and because of its huge success they want to host a second event on February 28, 2025.
To register for the hike led by a Blackacre naturalist, please visit their website: Calendar – Blackacre Conservancy
To volunteer with LAS at the event, please plan to bring a telescope and click here to send an email to the LAS Outreach/Sidewalk Astronomy Chair. The sunset will be at 6:35 p.m. that day, please plan to arrive between 5:30 - 6 p.m. to safely get to the field to set up telescopes. Hikers will end their hike in the field and will need help viewing the night sky. Blackacre provides refreshments.
TBA
We welcome the Public to join us at the James G. Baker Center for Astronomy in Curby, Indiana, one hour away from Louisville. Tonight the Waxing Gibbous Moon will be 70% illuminated and 9 days old in this lunation for observing through our telescopes. Jupiter and Mars will also be visible in the sky for observing.
This event is weather dependent so conditions may cause cancellation.
Map to Curby
The LAS welcomes one and all at our Star Parties. If you have a scope and are having trouble figuring out how to use it, please feel free to bring it to our public Star Party.
The LAS is an IRC §501(c)(3) tax exempt organization. Donations are welcome.
May your scope and skies be clear at the same time. Hope to see you there.
Telescopes will be set up after the meeting, weather permitting.
