Observation of the maximum of the variable protostar LRLL54361 at 70 and 16 micron

An extraordinary variable protostar discovered during our SPITZER variability campaign shows significant periodic brightness variation at PACS wavelengths. Our effort to cover at least two maxima during our OT2 campaignfailed due to severe straylight issues. That is why we request five epochs of photometer observation to cover the maximum of the lighturve of the source for the second time to confirm the amplitude changes that is expected based on the alreadyobtained data.
