This is aortic stenosis because they are listening over the aortic area and it is a systolic murmur. Rationally, it makes sense that aortic stenosis is systolic because in systole you would be attempting to push blood out through a stenotic valve and it would cause a murmur.
Likewise, aortic regurgitation is in diastole because it is during relaxation of the ventricle that the blood will be regurgitated back from the aorta to the ventricle causing a murmur.

Here is a diagram of the listening locations for each valve/heart murmur.
