In the aerobatic community we would call that the beginning of an Aileron Roll .
It's harder than it looks.

You do a roll change maneuver.
In German it is a " Rollwechsel ", and the time it takes to do this from -45° bank to 45° bank is an important measure for the agility of a glider.
The maneuver is meant to teach you how to quickly change the direction of circling, and for most gliders it limits the minimum size of their vertical tail surface.
The European certification regulations for gliders demand in section CS 22.147: Using an appropriate combination of controls it must be possible to reverse the direction of a turn with a 45° bank in the opposite direction within b/3 seconds (b is the span in metres) when the turns are made at a speed of 1·4 V$_{S1}$ with wing-flaps in the most positive en-route position, air brakes and, where applicable, landing gear retracted and without significant slip or skid.
Note the speed (v$_{S1}$ is the stall speed):
The faster you fly, the easier it is.
Since induced drag is highest at low speed, the adverse yaw resulting from the aileron deflection is impossible to overcome if you fly slowly.
Glider designers try to make the tail just big enough
so CS 22.147 can be fulfilled (the condition "without significant slip or skid" is crucial here!).
If you want to start an aileron roll this way: Please don't!
It takes a little more to roll a glider properly.

Here at the University we call it a "Perfect Roll", it is commonly used to assess the turning characteristics of an aircraft.

In Argentina we used to call it "coordinación" (coordination).

It sounds like the process of doing a slow roll, though the pilot usually does the role until they are at the 180 mark, that is inverted.

In addition to being (mistakenly) called a Dutch roll, I hear that maneuver called "rolling on a point" or "rolling on a heading.
" This is probably the most unambiguous description, as you are rolling the plane while using coordinated inputs to keep the heading constant.

My instructor made me do an exercise that consists of banking the sailplane left and right around 30 degrees without moving from the axis. I need to aim for a specific point, and start with the exercise. This is a coordination exercise but does it have a name? It's like a dutch roll but I need to stay in the roll axis without moving.
What is it called when you roll without yawing or pitching?

A roll without yawning or pitching is called a rool change maneuver, Roolwechsel in German, Perfect Roll, Coordinacion in Argentina, Rolling on point or Rolling on a heading. Although it is often mistakenly called a "Dutch roll", in English it is more correctly called a "roll change maneuver", a "Perfect roll" or "rolling on a point". It is also similar to the "slow roll", though inverted. The German equivalent is called "Rollwechsel" and in Argentina they call it "coordinación" (coordination).
