Just NW of Regulus. (Annotated)
Unfortunately the corresponding HL image is of no use in getting a parallax.

I'm not sure I know which "flash" you're talking about. Could you possibly label it?

I sure can.

The one above is labelled, the one below is a reference image taken around the same time. Note the "star" is missing.

There's nothing evident on frames before or after either.

Just "one of those things"?

We're looking into it.

Not sure what it is yet, it might be a burst star or something but we're really not sure yet.

Personally I think it's a head-on meteor, but it's still under investigation.

I do not think it is a head-on meteor, because it would have shown a definite trail from the other site. It could be a cosmic ray, and this could be checked by comparing its appearance with that of nearby stars of similar apparent brightness.

We've done just that... there's not much chance it's a cosmic ray hit, the point-spread function is just too star-like. Cosmic ray hits have much sharper edges.

Any update on this, Dan (or indeed anyone else)?
