We analyze archival ROSAT data of the CrA star forming region.
X-ray emission from five infrared Class I protostars in the
Coronet cluster was recently found in ASCA data, however, with
low spatial resolution and partly ambiguous source identification.
ROSAT high spatial resolution
data confirm the X-ray detection of three Class I protostars.
The other two infrared protostars might be extincted to strongly
for being detected in the softer ROSAT bandpass.
Alternatively, the X-ray emission might be strongly variable and
they might have been too faint in X-rays at the time
of the ROSAT observations.
