R CrB_1909

This light curve, compiled by VSS Director Colonel E E Markwick (JBAA 1910), shows the complex variations R CrB underwent during the 1909 minimum.
This is a timely reminder that during it's present minimum, R CrB can show interesting behaviour which is well worth monitoring closely.
The current minimum (see below) is close to an historical low!
