a detail of the image above, showing three different groups
of sunspots.
Another sunny saturday - time to photograph
our active Sun! With the number of big sunspots the possibility
of a geomagnetc storm is increasing, which might lead to middle-latitude
auroras, which I would like to see again after the great 2003
display.
The color was added to the image for better
visibility of features and to make it more appealing.
Attention: never look at the sun without a
proper solar filter, permanent eye-damage might occur!
