A friend gave me a plant from the nursery.
Where can I keep it in the houe I know not in a south window. But how much light? I have a room that gets morning and afternoon light. I know to put a pebble tray underneath it.
I had a few of these over the yrs. but have forgotten (senility I guess) what to do with it. TIA

Azalea, like rhododendron, prefers a filtered shade...when planted out of doors--behind a bush or tree and given protection from drying wind.

But indoors, in winter, the sun's power is low--the winter solstace is just two weeks away...the shortest day of the year, and it wont amount to much until about mid February so don't starve it for sunlight...just don't put it too close to the window glass which can magnify the sun's power.
Water it only as it requires it---and it wont take much during winter because its not growing--the sun has a lot to do with how much it grows.
Your eastern exposure is ideal. A peat based potting soil is also what it likes.
Keep it on the moist side...but not soggy, and never wet. When you water, be sure to let it drain...and don't let it sit in the drainage for long periods....otherwise, the water gets sucked up again around the roots.

Azalea is an acid living plant...its pH should hover around 4.5 to 5.5

Brown tips and leaf drop can be caused from overfeeding--which also might lead to weak stems and few blooms. Feed it only when it is growing and very sparingly.

Yellow leaves, if you notice them, can come from the soil not high enough in acidity.
But whenever you try to change the pH....do it ever so slowly...don't try to change it overnight.

Like other house plants, your azalea can be affected by how your furnace keeps the house heated. It will like warm days...and cool nights -- 55º - 65º. Keep it from being hit by air coming from an open doorway, window or from heat vent. A blast of cold air coming from outside can do much harm to houseplants--they like it the same every day.
In winter, because the sun isn't so strong, you can turn it a quarter turn every other day to ensure all parts get equal sunlight.

Very good info. Thanks
