Employees, students, family members and residents celebrated the summer in the inner courtyard on Sonnenstraße - and the sun itself seemed to join in the celebrations.
Children held their imaginatively painted faces up to the afternoon light or into the breeze at the bobby car ramp.
Adults swirled drinks and swung table tennis bats, chatted over apple and wine spritzers, played table football and enjoyed bowls and grilled food from the Studierendenwerk.
The welcoming of the new doctoral candidates on the stage in the inner courtyard and the opening of the poster exhibition(Opens in a new tab) "Studying - and then? Alumni report" at the student workstations punctuated the afternoon.
In the courtyard, visitors moved from the goal wall to wristband threading and from there to plastic duck fishing, for example.
With airy jazz from tenor saxophone, bass, vocals, cajon and piano, the "Klang Salon" trio underlined the increasingly soft orange of the evening sun from 6 p.m. and wooed the audience with "Fly me to the moon" and other temptations. Very informal, not swingless.
After them, the "Groove Delighters" turned up the volume to ten and rocked the audience with rousing, very danceable cover versions that made even the stiffest necks nod.
After them, DJs Max Berk and FH lecturer Oliver Seifert gave all those who wanted to dance a good reason to continue partying indoors.
