Re: HST observations of XTE J1859+226 - Oct 18 Dear Carole, Wan, Our Hokkaido colleague, Yasuo Sano (nytenmon@cocoa.ocn.ne.jp or sanoef@coral.ocn.ne.jp) is going to observe the source On Oct. 18, covering the HST exposure 11 and the RXTE GT starting at 08:36:00. The location of the observer is the best suited in Japan for simultaneous observations. He is going to perform time-resolved CCD photometry (he is an experienced observer, also known as the discoverer of the hypernova candidate SN1997ef). Coordinated optical photometry is also planned by the Kyoto group covering the preceding and following nights (Uemura and Kato). We are also calling for several potential observers. We will keep you informed (also via vsnet-alert) the progress. Regards, Taichi Kato Makoto Uemura
