This is an interesting one. It was discovered very early back on 21st April and is just hitting maximum light now. I took a spectrum on 27th April but could not then get a good match using the SNID classification software I usually use, possibly because it does not have many early spectra to compare with. Current spectra give a good match to type Ia now though and the brightness is bang on where it should be for a type Ia. Here is my spectrum (also in the BAA database as usual) and there is a more current spectrum here on the ARAS forum
