    Galaxy , Z=0.124, intense spectrum. Don't know what to make of this? Its so small.

    Strange weak spectrum, also referenced as supernova SN 2002il, but no host galaxy and still visible in DECaLS 😃 ?

    Must be something wrong somewhere

    The supernova had faded and there is only a weak signal from the distant galaxy. The supernova was only 0.002 arcmin from the host galaxy, so we must be looking at both at the same time.

    The supernova happened in 2002.

    The spectrum was taken in CE 2008 November 01 12:00:00.0 UT Saturday

    The supernova had faded, and is long gone. The chart is dim and full of noise

    DECaLS has better resolution, and we can see the host galaxy.

    I changed the title of this post to make to more informative.
