Here is my attempt to capture High resolution H-Alpha with the LhiresIII with 2400 m/l grating (18&21Apr18 data):

There is a noticeable notch on the 18Apr18 data around 6558A. This "notch" has decreased in intensity on the 21Apr18
data but is still present. I will attempt to hit this again, maybe around the Na doublet region to get any "dusty" event
that might occur.

Here are my last spectral observations of this interesting object, first, my last LISA observation (14Apr18):
Image
Please note that in my last LISA observations, I incorrectly noted high H-gamma activity. This is the HG line identified on this spectrum. As usual, all non-balmer lines are tentative spectral species.

Here is an animation I made from the LihiresIII h-alpha data taken between 18 and 28 April 2018:

Finally here are two spectra made around H-Beta(29Apr18) and the O1(27Apr18) lines:

Let me know if this look strange?
