     E. C. Olson, University of Illinois Observatory, writes that
near infrared and violet observations on Apr. 28 show return to the
'normal' state of last October.  Observations during Mar. 2-25
showed the system to be ~ 0.5 magnitude fainter than normal in the
infrared and ~ 1.0-0.5 magnitude fainter than normal in the violet.
