The Hellenic Astronomical conference is the biennial meeting of the Greek professional astronomers’ society. During the 11th version of this conference (held in Athens, Sep. 8-12, 2013), we contributed with a poster presentation on the need of pro-am collaborations for Jupiter and Saturn. In particular: “The need for Professional-Amateur collaborations…

Results (15/04/2015): Announcement (13/12/2015): The structure and variability of the upper atmospheres of the giant planets may be investigated by occultation techniques [1]. Ground-based photometric monitoring of stellar occultations measure the attenuation of starlight by the planet’s intervening atmosphere due to differential refraction. This requires a sufficiently bright star to act…
Polar caps: Both caps look bright, the south cap is brighter, and the north cap more extended than the south cap. SSTB: The white Ovals look bright. The oval between and north of A3 & A4 ovals(“Mickey mouse”) is still bright but less bright than at its discovery…
