searched the black pic

Finally had a go at Grace's photo... her potential aurora shot with her iPhone.

I stretched the completely black image but found nothing.

Shared my findings. Surmised that part of the reason was because the exposure time was 1/16th of a second. Way too fast. Said that normally, for aurora to show up, people do 20 or 30 second exposures.
