Proposal #386

Hello everybody,
I am asking here not for photometric observations (those are actually being done as we speak), but for spectroscopic observations, if they are available and feasible to carry on of course. As part of the team, Robin Leadbeater has captured, at the beginning of last year, some spectra of AS Cas. I really want a follow up set of spectra that cover from maximum to minimum brightness of this star. The epoch (JD at maximum) of it is 2459891.63619, and we have calculated with the aid of VStar using the DCDFT method a fundamental period of 3.0248 d, and a first overtone of 2.1555 d. With four or five spectra of this star will be more than enough. The idea is to confirm its spectral types at minimum and maximum. The format of spectra files can be either FITS or DAT. We are going to view them and compare them with RSpec's software.

This new spectra request is only for follow up purposes, and the idea is to contrast it with our data before the paper we are about to finish is submitted to a referee of the JAAVSO.

The magnitudes reported below are in Johnson's V filter.

Thanks!
