Caption: Figure 7.
Color–magnitude diagram from 2024 November 25, showing alerts from the night of 2024 November 24. Alert data points are plotted in front of a 2D histogram color–magnitude diagram of the Gaia catalog of nearby stars. Objects that passed all filter constraints from the SQL query posed via the Lasair API are plotted as orange squares. Objects that passed both the initial Lasair filter and the second round of statistical tests and other constraints beyond the brokers are plotted as purple stars. The letters correspond to the ZTF object names associated with each purple star: A for ZTF24abbldyz, B for ZTF24abjinpg, C for ZTF24abgzfsz, and D for ZTF24ablvgno. Note that point D is partially obstructed by the yellow diamond. Although not from the night of 2024 November 24, we plot ZTF24aaerzwh, our curious long-period variable, as a yellow diamond. This long-period variable is clearly situated on the main sequence.
