The comet Honda-Mrkos-Pajdusakova in that day was my first observation, positioned at 8 degrees southeast of Regulus. I could observe a condensed 7th magnitude coma and a long tail in WNW direction with its length of over 2 degrees. The comet has already passed perihelion, we will able to chase it from now on with good condition.
