NOVA CYG 2014

A newly-discovered star of magnitude 10.9 has flared in the constellation Cygnus the Swan. Koichi Nishiyama and Fujio Kabashima, both of Japan, made their discovery March 31 2014.

With that discovery, I chose this novae as my first nova/supernova spectroscopic project.  The novas official designation is PNV J20214234+3103296.  Using the C-14 telescope, LHIRES III spectrograph, and ST-8XME CCD camera.  I imaged each night, hoping to measure an increased or decreased output of various emission wavelengths .

In the wide field image below you can see how dense the star field is.  I use this field of view to find the target and move the telescope to have the target visible in the spectrograph guiding camera .  Then I center the target on the slit of the spectrograph with the guiding camera and collect the spectra with the imaging camera.

Below is one night of imaging.  A total of 12 images, 600 seconds long were processed, combine, and, calibrated to obtain the final graph. The strong emission lines of Ha=hydrogen alpha, NA=sodium , OI - (common in Fe novae), and O=Oxygen are visible.  Below the graph is the combined raw spectra images as the camera sees it. Then the emission and absorption lines of the entire range. As I process the additional nights of data collection I will update the page to show the changes in the novas output. Hopefully I will learn how to understand the results.
