LhiresIII observations

20120813_060_AZcas_Lhires_halpha MJD 56152.5596

Centered on h alpha (6502A-6608A) taken on August 13.06, with a LhiresIII spectrograph, 2400gr/mm, R=15000, disp 0,16A/pix, attached to a 0,212m f10 cassegrain reflector. Calibration has been done on a spectra of an internal neon lamp. Standart pre processing applied, instrumental response corrected with a spectra of Vega. not normalized.

Observers are Paolo Berardi and me during 2012 OHP spectroscopy workshop. No heliocentric and no telluric corrections. date MJD 2400000+

h alpha evolution

Heliocentric time evolution: 

20131127-201047-AZcas-3x1200s-TGarrel

 Heliocentric radial velocity/wavelenght shift variations,

Ew evolution between 6558 6565: Recent increase of the red wing emisison cause a decraese of Ew. Fluctuation before recent period are due to blue wing activitie with a probable period of 28d (to be confirmed)

Very nice set of spectra you have there showing the evolution of the Halpha line.

Might try to get a spectra of this star myself later this week :0)
