The first set of granulation images was observed at the
Swedish Vacuum Solar Telescope
(SVST) at La Palma with the support of G. Scharmer (Stockholm)
and in cooperation with G. W. Simon (PL/GPSS, Sac Peak).
The images show a few samples from 3700 frames observed between 8:07 and 19:07 UT on June 5, 1993 with a fast frame selection system. Wavelength was 468 ± 5 nm; the observed rms contrast of most frames ranged between 7 and 10.5 % (uncorrected). For a description of the series and some first results see Simon et al. (1994), in "Solar Surface Magnetism" (eds. Rutten and Schrijver), Kluwer, p. 261.
If you wish to get access to the whole series
just let me know!
These images were observed through a so-called G-band
filter (at 430.5 ± 0.6 nm) at the SVST La Palma by
G. Scharmer (Stockholm); they show finestructures down
to the resolution limit of the 50 cm telescope used, i.e.
near 0.2 arcsec or 140 km on the Sun. The tiny bright
structures probably represent magnetic flux tubes.
