  Context. EE Cep is one of few eclipsing binary systems with a dark, dusty
disk around an invisible object similar to {\epsilon} Aur. The system is
characterized by grey and asymmetric eclipses every 5.6 yr, with a significant
variation in their photometric depth, ranging from ~ 0 m .5 to ~ 2 m .0. Aims.
The main aim of the observational campaign of the EE Cep eclipse in 2014 was to
test the model of disk precession (Galan et al. 2012). We expected that this
eclipse would be one of the deepest with a depth of ~ 2 m .0. Methods. We
collected multicolor observations from almost 30 instruments located in Europe
and North America. This photometric data covers 243 nights during and around
the eclipse. We also analyse the low- and high-resolution spectra from several
instruments. Results. The eclipse was shallow with a depth of 0 m .71 in
V-band. The multicolor photometry illustrates small color changes during the
eclipse with a total amplitude of order ~ +0 m . 15 in B-I color index. The
linear ephemeris for this system is updated by including new times of minima,
measured from the three most recent eclipses at epochs E = 9, 10 and 11. New
spectroscopic observations were acquired, covering orbital phases around the
eclipse, which were not observed in the past and increased the data sample,
filling some gaps and giving a better insight into the evolution of the H
{\alpha} and NaI spectral line profiles during the primary eclipse.
Conclusions. The eclipse of EE Cep in 2014 was shallower than expected 0 m .71
instead of ~ 2 m . 0. This means that our model of disk precession needs
revision.
