Bulletin

Solar activity remains low. The only C-class flare reported during last 24 hours is C1.8 flare which peaked at 08:17 UT on September 19. From the currently available data it seems that flare originated from the Catania sunspot group 80 (NOAA AR 1836), situated just behind the east solar limb. The eruption from the Catania sunspot group 76 (NOAA AR 1845) at about 03:44 UT on September 19, has no reported flare. From the currently available data it seems that the CME is associated with coronal dimming, EIT wave, and it is possibly Earth-oriented. We expect flaring activity on the C-level. The Earth is currently inside a fast solar wind flow with the speed of about 600 km/s. The fast flow associated with the small equatorial coronal hole arrived in the afternoon of September 18. The low-latitude coronal hole in the northern hemisphere has reached the central meridian today. We expect arrival of the associated fast flow in the morning of September 22. The interplanetary magnetic field magnitude is currently stable having value of about 5 nT. The occasional intervals of negative Bz component of the interplanetary magnetic field, due to the arrival of a fast flow, resulted in unsettled to active geomagnetic conditions (up to K=4, as reported by local station Dourbe). The geomagnetic conditions are at the moment quiet to unsettled and expected to remain so in the following 48 hours.

Today's estimated international sunspot number (ISN): 044, based on 14 stations.
