Not quite yet; word will pass from the Germans trying to negotiate a surrender of Berlin up the Soviet chain of command to Zhukov, who will personally call Stalin and wake him up to tell him the news. Stalin's response:
"So, that's the end of the bastard."
“So, that’s the end of the bastard.”

Capture of the Reichstag (April 30, 1945)
At 10.40 pm on April 30 a Soviet victory flag was raised over the German Reichstag building in Berlin. It was not a real flag but a large piece of red cloth. The soldier who performed this act was Private Mikhail Petrovich Minin of the Soviet 3rd Army. There was no camera-man present.
The Soviet propaganda photograph we see today was actually taken later on the 2nd of May. It shows a Ukrainian soldier posing for the propaganda picture. This soldier had taken no part in the storming of the Reichstag.
Private Minin and a small group of five men (with a promise of the decoration 'Hero of the Soviet Union') were ordered to storm the building using a fallen tree trunk to smash down the front door.
Soviet troops hoisted the red flag over the Reichstag and over the Reich Chancellery - a woman did that, Major Anna Nikulina of the 9th Rifle Corps.
