| Abstract: | A sample of recent type Ia supernovae has been observed from La Palma. Spectra of there supernovae were taken at two different phases: around maximum and between one and two months after maximum. We present here our observations and discuss the existence of intrinsic differences within the sample.Paper presented at the 11th European Regional Astronomical Meetings of the IAU on  New Windows to the Universe , held 3–8 July, 1989, Tenerife, Canary Islands, Spain. |
