At that time, comet had a magnitude of 17.5. Before the end of the month, several observatories obtained follow-up observations. On October 29, IAU Circular No. 8003 announced this object to be a comet. Prediscovery observations were found on LINEAR images from October 12. On 30 April 2004, the comet was imaged and studied using the remote-sensing devices on the Rosetta spacecraft. The coma and tail were measured in wavelengths ranging from the ultraviolet to microwave. This occurred from a distance of about 95 million kilometres. The presence of water molecules around the comet was successfully identified.[1] References1. ^{{cite web|title=Rosetta's Scientific First - Observation of Comet Linear|url=http://www.esa.int/Our_Activities/Space_Science/Rosetta/Rosetta_s_scientific_first_-_observation_of_Comet_Linear|publisher=European Space Agency|accessdate=13 November 2014}} External links
