Partial Solar Eclipse on October
Weather permitting a partial solar eclipse will be visible here
in Indianapolis on Thursday October 23rd. The eclipse will
begin roughly an hour before sunset. Thus inorder to see the
eclipse we suggest you find a location with an unubstructed western
horizon. The exact timings of the eclipse are given below.
At mid eclipse, which occurs near sunset, roughly 50% of the
Sun's disk will be covered by the Moon. Unfortunately the Sun
will set shortly thereafter which is why it is imperitive to have a
clear western horizon to view the eclipse.
Our Viewing tips:
- Hope for clear skies with very few clouds.
- Find a location with a clear/unubstructed western horizon.
The sun will be approaching sunset so this is a
- Use a safe method to
view the eclipse. Warning:
Never look directly at the Sun with binoculars, a telescope, or
your unaided eye. Serious eye damage can result.

Holcomb Observatory and Planetarium has been serving Butler
University students and the Indianapolis public for 60 years. The
observatory, one of the largest public observatories in the world,
houses a 38-inch Cassegrain reflector in addition to a number of
smaller telescopes. It is the ninth largest telescope East of the
Mississippi River. The observatory can be visited during our
regular public tours listed above or groups can schedule private tours at other times.

During 2014 the main telescope will be undergoing a
$325,000 refurbishment by Astronomical
Consultants and Equipment. We will still continue to have
telescope viewing and planetarium shows as usual. A
portable computer controlled telescope will be used for viewing the
planets, Moon, and stars. This telescope gives us great views
of the planets! We are looking forward
to having our greatly improved main 38-inch telescope
back online in early 2015. See the tab to the lower left
for more information about the upgrades.
