Using "Wien Moosbierbaum Luftangriff Januar 1945" to search Google with language preference GERMAN, I turned up 371 hits. The best is this one: http://www.geheimprojekte.at/t_dora.html .

According to these sites, the 31 January raids (2 of them) caused very little damage. It was the raid the next day, 1 February, that clobbered the synthetic refinery, with 1,200 to 1,500 bombs on target. Production at the plant was disasterously reduced. Again, no mention what so ever of fighter interception and it appears no claims were made by the Flakartillerie either. The plant was heavily defended by Flakuntergruppe Moosbierbaum, which consisted largely of RAD batteries.
