IGR[7] C observation. Night is clear and the narrow Moon just left the horizon... Hour before dawn I switched to M 15 (R) for a while...

Add CY Aqr: I just finished some periodogames with Peranso. CY Aqr was found to be humping at aprox. 85.4 minutes which is in good agreement with literature. More precise result could be obtained while combined more nights, maybe I'll do some other run but it is not likely now. Right now I'm not sure about possible maxima amplitude changes and small variability of a check star. Maybe more detailed studies were performed so I'll check the ADS to focus/unfocus this target.

Experiment with MAT file. Mag vs log(st.dev). Looks good...
