Bulletin

Solar activity is very low. Only two B flares were observed over the past 24 hours. Five active regions are presently observed on the visible side of the solar disc. Their photospheric magnetic field configuration is simple (beta and alpha configuration). One narrow fast CME coming from the East limb was detected by CACTUS at 17:48 yesterday (15-Aug-2016) originated by an eruptive prominence from the NE limb as observed by ADO/AIA imagery. No geoeffective effects are expected. The high speed stream originated from a low latitude coronal hole has not interacted with Earth geomagnetic field. Solar proton flux intensity is expected to lie within the background levels. Solar activity is expected to be low with small probability for C-class flares.

Solar wind speed continued to decline till 310 km/s as observed around 12:00 UT today (16-08-2016). The magnetic field intensity (Bt) remained below 5 nT. The Bz component was mostly positive or neutral. The local K index at Dourbes was ranged between 1 and 3 (planetary Kp index was ranged between 1 and 2) during last 24 hours. The solar wind parameters are expected to be low and geomagnetic field to remain quiet and undisturbed.

Today's estimated international sunspot number (ISN): 083, based on 23 stations.
