Solar Observing Session Information
Solar observing sessions will be held in the late morning/early afternoon for one week at the Campus Observatory, southeast of Foellinger Auditorium. Observing will take place on the south lawn of the Observatory (between the Observatory and Morrow Plots) using telescopes with specially-designed filters. These filters block 99.999% of the sunlight and make it safe to observe the Sun. Astronomy Department personnel will be present to operate and explain the telescope and the solar phenomena being viewed. Freely ask questions and sketch what you see.
Dates & Times
The scheduled dates for solar observing are listed below.
- Monday, November 4th - CLOUDY
- Tuesday, November 5th - CLOUDY
- Wednesday, November 6th - CLOUDY
- Thursday, November 7th - OPEN!
Due to cloudy weather, additional sessions have been scheduled for the following dates:
- Monday, November 11th - CLOUDY
- Tuesday, November 12th - OPEN!
- Wednesday, November 13th
Solar observing sessions run from 10:30am - 1:30pm each scheduled day (unless otherwise noted). You may arrive when you wish, but be sure to allow approximately 20-30 minutes complete the observations before the end of session.
All are welcome to look through the telescopes, including your friends.
Observing can be done only if the sky is clear. Sometimes it will be clear an hour before a session is to start, only to cloud over in the next hour. At other times the sky is cloudy at the time we want to open the observatory and it clears up after the TAs have left. It is obvious to say that the professors and TAs who are involved cannot control the weather, but we try to cope with the circumstances as best we can.
Also, if the temperature is under 20 F, the session will be cancelled.
