We are interested in observations at the disc center during 24 to 48h if possible, with a time step of 30 to 60 seconds in G-band, with a pixel of 0.16 arc, and if possible magnetograms, blue and red continuum and at least CAII H line. Our estimation of 1 image/minute, which is the minimum time step we need, with a pixel of 0.16 arcsec gives 107Mb/hour and 2.56Go/day. This gives a rate of 237 kb/sec which seems compatible with the mean Hinode rate 300kb/sec. In order to follow the evolution in time of the families properties during the solar cycle, we would be interested by one or two observations per year during the increasing phase of the cycle.
In addition in future proposal, it could be envisaged some observation at two or three latitudes to try to find connection between meridian flow and supergranulation. |
