Further: note that the proposed rotation period of only 25 seconds implies that exposures of only a few seconds will be needed to get a good light curve. In practice, this suggests only 0.7m-class or larger telescopes will be able to do this successfully, likely implying the use of robotic telescopes.
Getting colour indices, on the other hand, should be somewhat easier as exposures >25s will average out the rotational behaviour. This could be a productive use of personal telescopes fitted with two or more standard photometric filters.
My thanks to Richard Miles and Tomasz Kwiatkowski for the further information.
