I read that one year ago a thirty second flash of a supernova in the constellation Bootes was visible?

on Earth. What did the flash look like? Compared to the other stars in the sky at the time. I don't suppose it was recorded on video?

Thanks.I read that one year ago a thirty second flash of a supernova in the constellation Bootes was visible?It was a gamma ray burster rather than a supernova and it was captured on video. Look at this website: http://science.nasa.gov/headlines/y2008/鈥?/a>I read that one year ago a thirty second flash of a supernova in the constellation Bootes was visible?Supernovae usually last longer than 30 seconds. They generally go for days to weeks and consist, within the visible spectrum, of a relatively dim star growing brighter by several magnitudes. Perhaps the 30 second portion was just the peak of the light curve.I read that one year ago a thirty second flash of a supernova in the constellation Bootes was visible?That's the first I've heard of it, and I belong to the AAVSO which tracks such things. There are supernovae observed in other galaxies all the time, but very few galaxies in Bootes. There's no such thing as a supernova lasting only 30 seconds...they take a few hours to reach maximum brightness and then weeks to fade away. I think you must have misread or misunderstood.
