Continuum images extracted from four unprocessed scans, obtained by directly summing 40 raw spectra for each vertical image line, each spanning a period of about 400 ms, thus covering a period of approximately 600 s for each scan. Top left: newly emerging AR at disk center, top right: trailing plage of AR12436, located at μ = 0.82, bottom left: main spot of AR12436 at μ = 0.69, bottom right: a small plage region towards to the east limb, at μ = 0.53.
