Let an observer B on the star estimate the distance and epoch of the nova outburst to be x<nowiki>'</nowiki> units of length and t<nowiki>'</nowiki> units of time, respectively. Then the Lorentz formulae, relating x<nowiki>'</nowiki> to t<nowiki>'</nowiki>, are<center><math>x' = \frac {x-vt}{\sqrt{1-\frac{v^2}{c^2}}} ; \qquad t' = \frac {t-\frac{vx}{c^2}}{\sqrt{1-\frac{v^2}{c^2}}}</math></center>
These formulae are... quite general, applying to any event in line with two uniformly moving observers. If we let c become infinite then the ratio of v to c tends to zero and the formulae become<center><math>x' = x - vt ; \qquad t' = t</math></center>.

“This is a terrific outburst. And since it doesn’t have a tail right now, some observers have confused it with a nova. We’ve had at least two reports of a new star.”
As quoted in "Dramatic Comet Outburst Could Last Weeks" (26 October 2007) by Robert Roy Britt at Space.com http://www.space.com/spacewatch/071026-comet-holmes-update.html.
