Global Jupiter Campaign

We would like to enlist your help in observing Jupiter during a short window of April 13-17. This observing window will enable us to try a “dress rehearsal” of a global observing project. If you can observe Jupiter with a video camera for 3 or more nights within this window, it would great!  Franklin Marsh, our student from Pomona College, has kindly agreed to reduce all the data, which will be uploaded to a site on Google Drive. We have created a Google Account “” in which we will be able to keep resources and data for the project.

 The basic observing strategy is to gather short segments of  30 seconds to 1 minute of video at a sharp focus of Jupiter on 3 or more nights within this window. The results should be saved with the .avi format, and you can upload the video files to Google Drive with file names such as jYYYY-MM-DD_filter_observer.avi.  (More instructions will be sent closer to the date).

 We will gather these movie files and reduce them using the techniques described by Chris Go at our workshop in Singapore using WINJUPOS and Registax. In case you want to review some of this the presentation is available at: It is also on our GONSSO web site at

 If you would like to participate in our Global Observing Campaign, can you take a quick moment and fill out our survey? The survey just confirms the dates when you can observe, and asks for contact information for your lead observer and a few details about the telescope and instrument you plan to use.  This survey is available at:

 Thanks again for your participation – we are looking forward to our Global Jupiter Campaign – April 13-17, 2015!  If you have any questions – please email them to be at or to Franklin Marsh at


We also have prepared a document that describes how to participate and the formats for files and procedures for uploading the data. This document can be uploaded at this link: global_memo.
