  We present and analyse the sunspot observations performed by Franz I. C.
Hallaschka in 1814 and 1816. These solar observations were carried out during
the so-called Dalton minimum, around the maximum phase of the Solar Cycle 6.
These records are very valuable because they allow us to complete observational
gaps in the collection of sunspot group numbers, improving its coverage for
this epoch. We have analysed and compared the observations made by Hallaschka
with the records made by other contemporary observers. Unfortunately, the
analysis of the sunspot areas and positions showed that they are too inaccurate
for scientific use. But, we conclude that sunspot counts made by Hallaschka are
similar to those made by other astronomers of that time. The observations by
Hallaschka confirm a low level of the solar activity during the Dalton minimum.
