Comments on spectrum and activators:

The green SW fluorescence is most probably due to uranyle ions contamination.

Best localities for fluorescence (*):

• Pune (Poona) District, Maharashtra, India;
• Challis, Bay Horse District, Custer Co., Idaho, USA (bright reddish-pink LW, nothing SW, cited by De Ment);
• Southeast Quarry, North Table Mountain, Golden, Golden District, Jefferson Co., Colorado, USA (yellowish white LW);
• Roadcut near Montresta, Oristano Province, Sardinia, Italy (LW white + SW green);

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
