[vsnet-obs 58188] gamma Cas

[ErnstPollmann at aol.com]

Gamma Cas shows steadily rising Halpha EW since 2006/06.   
Upper fig. in attached monitoring shows measurements of  the past decades, 
comparing also made with professional  instruments. 
Dr. Myron Smith has suggested to observe the intensity of  the HeI6678 
emission (attachment, middle fig.) in order to get information about  possible 
correlation to Halpha (attachment, lower  fig.). 
At least in this observed period (2003/04 - 2007/05) no  correlations are 
detectable.
