R -  relative number: refractor Coudé 150/2250 mm, projection methodi susedwith a diameter of the Sun 25 cm
O -  image quality: 1  - the worst image and 5 – the best image according to the following scale:
                                 1 – only big sunspots are visible, granulation isinvisible,
                                 2 – smaller spots are visible, sometimes the granulation also,
                                 3 – tiny spots are visible, granulation is well visible,
                                 4 – granulation and pores are well visible,
                                 5 – all details are well visible.

EMP – Earth’s magnetic field:  H-variometer is used to register disturbance of the horizontal component of the EMP. We evaluate regularly eight 3-hour intervals between 6.00 UT of the actual day and 6.00 UT of the following day. We report the following status for the disturbance:
np -  non-disturbed,
mp - moderate disturbance,
stp - strong disturbance,
sip - severe disturbance.
