Richard Christopher Carrington
Richard Christopher Carrington (
May 26 1826 –
November 27 1875) was an
English astronomer who discovered the differential rotation of the
sun by means of
sunspot observations in
1863. In
1859 he already was the first one to see a
solar flare and suspected its connection with a
geomagnetic storm observed later that day. Even though Carrington did not discover the 11 years sunspot activity cycle, his observations of the sunspot activity after he heard about
Heinrich Schwabe observations led to the numbering of the cycles being done with his name. Thus the sunspot maximum of 2002 was of the Carrington Cycle #23.
