MINUTE 142th BRIEFING: 15/06/2015, 14H30
SUN Previsor 1: During the period 09th-15th June, in the most of days, DESPITE the six activeregions on the solar disc, only one presented either a complex or relatively complex magnetic configuration, with a moderate potential to generate moderate to intense flares. On 9th June, a partial halo CME – probably associated to the C2… Continue lendo MINUTE 142th BRIEFING: 15/06/2015, 14H30
MINUTE OF 138th BRIEFING: 04/05/2015, 14H30
Space Weather Exhibition Room/INPE-SJC SUN Forecaster 1: During the Last week (April 28th to May 4th) was observed two coronal holes. The first CH665 was geo-effective on May 02nd and the second was located over Southern Hemisphere. We observed a CME directed to Earth on May 2nd. The community estimated that this CME would arrive… Continue lendo MINUTE OF 138th BRIEFING: 04/05/2015, 14H30
The complexity of three solar Magi Kings
Authors: Rafael R. S. de Mendonça, Carlos R. Braga As well as the Three Magi Kings, three coronal mass ejections (CMEs) left their birthplace (the Sun) and passed the Earth during the last Christmas. The first CME (Melchior) was ejected on day 17th, the second (Balthazar) on 19th and the third (Caspar) on 20th of December 2014.… Continue lendo The complexity of three solar Magi Kings
Van Allen probes (RBSP) measurement of the radiation belt dynamics
Sponsor: Dra. Ligia Alves da Silva The Outer Radiation Belt consists mainly of high energy electrons (0.1-10 MeV) trapped in the Earth’s Magnetic Field. Its almost toroidal shape extends from ~3-10 Earth Radii (Re). The Figure (1) shows the energy flux of the 3.60 MeV electrons for the October 17th-28th (2014) period, observed by instruments… Continue lendo Van Allen probes (RBSP) measurement of the radiation belt dynamics
Auroral activity in October 2014
Sponsor: PhD Cristiano Wrasse On October 14th, 2014, the Kp index reached level 5, and the auroral AE index ranged 500-1000 nT during, 21:00 to 23:00 UT, considering the disturbed geomagnetic activity, with scale G1. See the details of the variation of Auroral index in Figure 1. On the night of October 14th , between… Continue lendo Auroral activity in October 2014
Magnetometer’s network of EMBRACE recorded intense activity between 13/10 days to 21/10 days
Sponsor: PhD Lívia Alves Geomagnetic field has been more active during October when we compare with the previous months. Kp index reach 3 and 4 during several days on last weeks. Mid and low latitudes regions also shown an increase in activity, for several days Dst reach around – 50 nT.
NanoSatC-Br1 (Brazilian CubeSat Project-1)
NanoSatC-Br1 is the first CubeSat project of Brazil, developed at the Southern Regional Space Research Center (CRS/CCR/INPE-MCT) in collaboration with the Space Science Laboratory of the Federal University of Santa Maria (LACESM/CT – UFSM), Santa Maria, RS, Brazil. The INPE (Instituto de Pesquisas Espaciais) South Regional Center is in fact located on the campus of… Continue lendo NanoSatC-Br1 (Brazilian CubeSat Project-1)
Geomagnetic storm mystery solved: How magnetic energy turns into particle energy
Magnetic reconnection can trigger geomagnetic storms that disrupt cell phone service, damage satellites and black out power grids. But how reconnection, in which the magnetic field lines in plasma snap apart and violently reconnect, transforms magnetic energy into explosive particle energy remains a major unsolved problem in plasma astrophysics. Magnetic field lines represent the direction,… Continue lendo Geomagnetic storm mystery solved: How magnetic energy turns into particle energy
