One C-class flare in past 24 h: C1.9 peaking at 12:51 UT on April 28, from NOAA 2535 (Catania 63). More C-class flares are likely.

Several CMEs occurred in the past 24 h, directed towards the north-east. Two of them on April 28, originated in the vicinity of NOAA AR 2335 (Catania 63). These are not remarkable events, but due to the proximity of the AR to the solar disk center, they require some attention. The first one at 02:12 UT (LASCO-C2) was very slow and faint, no Earth effect is expected. The second one at 07:12 UT was also slow and most likely will not affect the Earth, but a glancing blow around May 2 cannot be discarded. A filament erupted from the eastern limb at 12:00 UT on April 28 (after a slow rise), the corresponding CME is not expected to affect Earth. Finally, on April 29, a CME erupted at 05:00 UT, this event is probably backsided (more data needed) and will not affect the Earth.

Geomagnetic conditions have been quiet. The solar wind speed is at 375 km/s with interplanetary magnetic field magnitude around 5 nT. The arrival of a fast speed stream within 48 h is expected to create minor storm conditions.
