1122:, The coma size values plotted at the bottom of this page are primary measurements. They were obtained using conventional methods: individual short CCDs images were made in order to avoid saturation, and these were then calibrated with bias, flat, and dark frames and summed to increase the image dynamic range. Each stacked image (for the 5 nights of data) was astrometrically calibrated (using Pinpoint) for scale, and the intensity profile of the coma measured with a standard tool (in this case, the line profile tool in MaximDL). The resulting profiles were exported to Excel, normalized to the same gain, and the width measured against the noise floor. The best reference is the plotted data itself.

Although large telescopes had already shown fine-scale cometary details, naked-eye observers saw Holmes as merely star-like until
October 26. After that date, 17P/Holmes began to appear more comet-like to naked-eye observers. This is because during the comet's outburst, its orbit took it to near
