Early Nov Sun and Bloom Blast

[Gil]

Have had Phal's on my window ledge indoors during the cold season for many years but never had a late fall bloomer. Since I have increased my collection I have a few now. This young stuartiana "Sogo" was coming along nicely up to a few days ago. Then this morning I checked and noticed that the buds are blasting. My only thought is that the sun was too strong yet for the small flower buds. I have some other plants in spike now and am beginning to get concerned about the affects of the sun on them. I have an option of moving them to a somewhat shadier area to prevent this from occurring again.
The window is tinted (I don't know by how much) but does allow fairly good sunlight through it. This orchid was getting about 3 to 4 hours of morning to near noon sunshine through the southeast facing window.
Was hoping the buds were just coloring up but it looks like the handwriting is on the wall for them.
