Observation Calendar and Table

Year summary of the campaign observation plans. The approximate number of plans scheduled for each day is reflected in the day's color: white for no observations, increasing from brown through black. There is a clear peak in the number of observations near the comet's perihelion in late-November, but also subtle peaks in early-October and eary-November (coincident with new Moon). The full figure includes 2012 and 2014.

During the ISON Campaign, we collected observing plans from professional astronomers observing Comet ISON to facilitate collaborations and enhance the scientific output of everyone's observations of the comet. The observation plans are summarized below in a calendar and table. Note that only day precision is given and the dates are specified in UT. All the details are listed in the observation table.

Amateur astronomers were encouraged to participate in the campaign via Padma Yanamandra-Fisher's Facebook Group, and the Amateur Observer Program at the University of Maryland.

Note: The plans summarized below were voluntary and often changed during the campaign: nights could be weathered out, data could be affected by spacecraft glitches, the comet may disintegrate(!), etc. Our website does not host data, but does show some of the pretty pictures. Please be patient while astronomers consider the data they have taken, and make the most of this opportunity. For more comments, see Karl Battams's Blog Post: Show Me The Data!

During the campaign, we created a Google Calendar with all observer plans. The final version of the calendar can be downloaded as an iCalendar formatted file.
