As a key component of your Astronomy lab is to learn about and gain an appreciation for observing the night sky and astronomical objects, Clear Skies observation nights are held on select Sunday-Thursday nights in the first half of the semester. For Clear Skies, you may instead attend a Department of Physics and Astronomy Public Observing Night. Take notes the night of the observation and complete the worksheet provided.

You must register for the Clear Skies event of your choice by emailing the Astronomy Laboratory Coordinator Dr. Caroline Roberts from your UI email ( stating the date you are signing up for and the name of the class you are registered for (ASTR:1070/1079 Stars, Galaxies, and the Universe, ASTR:1080 Solar System Astronomy, or ASTR:1771: Intro Astronomy I: Basic Astrophysics). A couple days in advance of the date you signed up for, you will be sent an email confirming the details of your observation. Some Clear Skies nights may be cancelled for various reasons, including weather; you will receive an email if your Clear Skies is cancelled. Clear Skies space is limited to 36 students per session. Sign up for a Clear Skies night sufficiently far enough in advance that if it is cancelled, you still have time in the semester to attend a second night that still has availability. Note that space is unlimited at the Department of Physics and Astronomy Public Observing Nights.
