Partial Solar Eclipse on October 23rd

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:

  1. Hope for clear skies with very few clouds.
  2. Find a location with a clear/unubstructed western horizon.  The sun will be approaching sunset so this is a must. 
  3. 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.  Please go to the tours tab to the right for more information.

During most of 2014 the main telescope will be undergoing a $325,000 refurbishment.  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!  This Spring our two main targets are Mars and Jupiter.  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.
