Really, it is a nice image. As for correct orientation, I think that 2 vectors should be given.
Which way is North?
And because some S/w flipps an image, which way is either East or West.
IMO just giving north, is insufficient. Taking a cue from 'The Sky', if both North and East vectors are given, this will allow accurate comparisons to be made world wide.
Is there a link detailing how sunspots are numbered??
Cheers,
Doug
