CN And CWA_CB According to lc from Jassur & Khodadadi [352] it is a CBV system because of asymmetry (primary maximum is greater than secondary) and large dA, but according to lc solution it is CWA overcontact system with components in poor termal contact. ... According to Coughlin et al. [354] is a marginal contact system with both components almost fill their critical lobes, light curve asymmetric, so authors use hot spot on the primary to solve light curves. ... So It may be the CW system. ...
... This applet generates an observing list based on an observer's location and time. ... To use this program, enter in your location, and the local times at which you wish to begin and end observing. The date you enter should correspond to the calendar day at the time at which you begin observing. For example, if you wish to observe from 9:37 PM October 23, 2007 until 3:21 AM October 24, 2007, you would enter 21:37 for the starting time, 03:21 for the finish time, and 10/23/2007 for the date. ...
