Cumulative classifications per day on Kilonova Seekers from launch until the end of O4a (2024 January 16). The first (blue) shaded region corresponds to the dates of press releases, and active media coverage of the project during the launch period. The second (red) shaded region towards the end of September shows the maintenance period after three months of operations, when we temporarily paused the scheduled uploads and implemented the Gen. 2 subjects based on feedback from the volunteers. The third (green) shaded region highlights the increase in rate of classifications over the winter holiday period and the subsequent return to work. The solid vertical line corresponds to the date of an email newsletter sent out to registered volunteers, leading to a clear increase in classifications. The dashed line is the date we increased the data upload cadence from twice per day to every three hours.
