I cannot resist to present my experience on this subject as I have  grown
commercially since 1990 about 10000 bulbs of Sternbergia  lutea
angustifolia. In the early years multiplied  by cutting the bulbs, which  is
done the end of June for planting out end of July.

They need a sunny position from Sept-April. So I think that yours are ok
where they are.
However, I strongly disagree with the advise given to move the bulbs now.
First roots emerge  during August and are by now well developped, leaves
will be out next week. The plant has already spent a part of its reserves
will suffer by making new roots. Once a replanted some Sternbergia in
Octobre which was disastrous as that that time the bulb has completely
depleted its reserves.
The best planting time is without any doubt from May until the middle of
If your bulbs are now too close to the surface, you could for this season
cover it with 10cm(4") of mulch  (straw,compost etc.) and transplant the
bulbs next May.  I lift the bulbs every year by the end of April and replant
early August, immediately covered wit a layer of straw. At the moment they
are in full flowe which is rather an impresssive sight.
I hope that this is of any help.
