Subject: Re: HIGH CADENCE IMAGING CAMPAIGN Date: Sat, 13 Apr 2002 14:23:38 +0900 From: KUROKAWA Hiroki Organization: Kwasan Observatory, Kyoto University To: Richard Canfield CC: observer@kwasan.kyoto-u.ac.jp Dear Prof. Canfield; Thank you for your calling our attention to the coordinated obsevations with RHESSI. Actually we are planning to get high resolution Halpha images of flares with RHESSI. We will use the following two telescopes. (a) the 60cm Domeless Solar Telescope at Hida Obs. (b) the 18cm Halpha Telescope at Kwasan Obs. The temporal cadence of these telescopes are about 1.5 s for the flare mode. Other informations of our observational scheme with these two telescopes are answered in the followings. > 1. What field of view can you observe at this cadence?

(a) It depends on the date and the week. a Target-of-Opportunity campaign is possible if the dates are not allocated to any visitors or any other specified campaign. (b) Yes. > 5.

Thank you for your arrangements. H.
