2 BORÓWIEC SRC PAS astrogeodynamic observatory φ = N λ = E h = m

3 Additional Diagnostics POLISH LOFAR STATIONS Scintilation reciver, Riometr Ionosondes, Warsaw, Olsztyn, Spitsbergen(Horsund) Radio reciver for DAB and oblique sounding

4 1. Research subjects out of CBK s interest: analysis of ionospheric and magnetometer scintillations. Results of both theoretical and observation analyses data will serve to this phenomenon s model construction and will be applied both in making ionospheric corrections at radio astronomy observation corrections and in Space Weather services. 2. Solar Wind parametres analysis, mainly an intraplanetary scintillation analysis. That to verify data provided by an American mission IBEX. 3. Sun s radio frequency analysis, in particular its solar radio burst. 4. Analysis of electromagnetic noise and pollution close to Earth. Apart from measurement data from LOFAR, ionospheric diagnosis located in a station and other ground equipment: ionosondes and digital radio receivers have been used here. 5. Jupiter and other Solar System s planets radio frequency analysis and radiation diagnosis of Jupiter s radiation strip. Those have just been coordinated within the world earthly enhancement programme of the mission NASA JUNO towards Jupiter. This activity has been conducted within EUROPLANET, the Paris Observatory being the closest partner in cooperation. That work may be helpful in ESA s scientific programme s preparations of JUICE mission. 6. Space mission design to take advantage from the rules of interferometry applied in LOFAR s infrastructure and to create a complementary LOFAR for the outer space. That works will be useful for two Projects: NCLE i DLSP missions of China Space Agency Chang E-4 towards the Moon s neighbourhood. That has been the subject of cooperation with ASTRON and the University of Nijmegen in Holland.

5 Technical activities Local observation depository computers and adequate software were installed. Replacement of local LCU system Identification MHz RFA for selected LBA antennas and some different action for mitigation this effect. Removing a computer switch failure

6 RFI Some part of LBA antennas located near observation building are affected by power supply located in the basement

7 Local observation activity - software to manage the station on a local basis to facilitate its independence - software to create dynamic spectrum in real time - measurements of EM waves scintillation on irregularities of plasma in Solar Wind - possibility to use the Transient Buffer Board (TBB) to parallel observations - possibility of creating dynamic spectrum based on previous data registry; special software development was applied to test the above.

8 Local observation activity - In cooperation with a University in Bielefield pulsar observation was initiated - observation of ionospheric scintillations based on strong radio sources; the options of various station configurations were checked

9 Local observation activity -the Sun observations were made to check the optimum capabilities to monitor Solar emissions - the observations of Jupiter at low frequencies were made to proceed in DAM observations (dacametric radio emissions) - sources of electromagnatic radiation within the short-wave range were monitored

10 VESPA implementation workshop , Graz, Austria VESPA - Virtual European Solar and Planetary Access LOFAR PL610 observations of decametric Jupiter radio emissions will be avaliable via VESPA platform with open acces. Measurements will be a part of followup monitoring for space mission JUNO. In future also observations of solar radio emissions will be available. SRC PAS will also provide space weather alerts.
