Bulletin

Two simple active regions (AR) were noted, called NOAA 2559 and 2560, which did not produce any events. A CME was observed, associated with an increasing Xray flux and filament parts erupting near N10W35. The CME (first measurement at 20:48 UT in LASCO/C2) has an angular width of 100 degrees and is travelling northwest of the Sun-Earth line with a projected speed of 380 km/s (CACTus estimate). No influence is expected for the Earth environment. The probability for flaring activity at the C-level is still low.

Earth is currently inside a slow solar wind, with the speed gradually declining to values near 330 km/s. The magnetic field magnitude is around 5 nT. The solar wind is expected to remain so till the onset of a co-rotating interaction region (CIR), followed by a high speed stream (HSS), expected on June 7. Geomagnetic active (K=4) to minor storm (K=5) conditions can occur on June 7 and 8.

Today's estimated international sunspot number (ISN): 011, based on 18 stations.
