%X We present a preliminary table of mean values of the F2 region bottomside parameters B0 (thickness parameter) and B1 (shape parameter) for the time interval 00.00 LT-23.00 LT. Data from vertical ionospheric soundings at Havana (23¡ãN; 278¡ãE; Dip 54.6¡ãN; Modip 44.8¡ãN) during wintertime and low solar activity (R12¡Ö15) were used in the study. The diurnal variation of B0 shows higher values during nighttime than during daytime. The B1 parameter tends to be lower during nighttime than during daytime.
