[AAVSO-HEN] GRB080328 OT (2nd opinion)

After reading my earlier post Arto Oksanen emailed a request to see  
my images.

I was hesitant to share them because they are not the best quality  
(the GRB was so low in my sky that part of the aperture was looking  
at my observatory wall, plus I was in such a rush I didn't take time  
to get a good focus).

But I did send them and Arto says he can see the GRB (albeit very  
faintly) in at least one of the images.

If other would care to have a look I have posted the reduced (master  
dark and flat applied) FITS images at:

Plus Arto has posted them at:

http://murtoinen.dyndns.org/ccd/Arto/grb080328/

Arto also prepared small JPGs showing the field in a Digital Sky  
Survey R-band:

And the same field from one of my images with what he suspects is the  
GRB indicated:

Image scale is 1.1"/pixel.

All opinions welcome,
