A very interesting sun. Active Regions 1242 and 43 are very pronounced today. A lot of proms including a nice very tall but faint prom at the Western limb and a hedge row at the NW limb. The row of individual proms seems to be duplicated by a row of filaments paralell to the proms on the surface of the Sun.
