Procedures for observing

Welcome!

We are delighted you are involved in our Global Jupiter Campaign! If you would like to join our global Jupiter campaign, please follow the steps below.  You can also download a memo containing all these instructions at this link: global_memo

First – let us know (if you have not already) by sending an email to both Bryan Penprase and Franklin Marsh at the email addresses below, letting us know you are participating:

Franklin Marsh: fmm02013@mymail.pomona.edu

Bryan Penprase: bpenprase@pomona.edu

Data Capture

Each observatory will have different cameras and telescopes, some of which have been outlined in our Google Form. If you have not done so yet – please take a moment to describe the instrument and telescope you are using at our Google Form which is located at http://goo.gl/forms/f3ykRCFypZ. For optimal focus and image quality – please try to use the maximum magnification possible, and a narrow-band or broad-band filter will help with the sharpness of the image. The only definite requirement for the video data is that they are captured in .avi format, so a wide range of cameras and instruments should be usable for our campaign.

Simply acquire and focus Jupiter using a video imager, and take 1 minute of data at the highest feasible framerate. If you are using a filter in front of the camera, note the filter used. Record the time that each video was captured, or better yet, record it into the filename.

If you have any questions about the process of video imaging, let us know. Both Franklin and Bryan can help out with emails to our addresses above. This presentation by Christopher Go (hosted on the JUNO website) is a fantastic resource for those interested in learning more about planetary imaging:

File Upload

To upload data, you have two choices. One is to email us a link to the files as they exist on Drop Box. The other would be to upload the .avi files to the google drive within the account known as observe.jupiter@gmail.com. We will be delighted to share the password for the account, and we will be posting the reduced data as well to this site. Please email us for that password.

In either case we would like to request that you use a definite file naming protocol. Data files must be named according to the following scheme:

jYYYY-MM-DD_filter_observer.avi

Where “j” indicates the target Jupiter, the date is in year, month, day, format, and the filter codes are r,g,b for Red, Green, and Blue, and ch4 for the 890nm methane band.

Data Reduction

After the campaign, our team at Pomona College and Yale-NUS College will post process all of the raw videos and produce images and maps, that I will provide to Glenn Orton for evaluation and feedback. Hopefully, this short test run will allow us to work on improving collaboration between the observatories, and give us a flavor for what kind of data the telescopes on the network can produce!  It should be exciting!
