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…
This work is a collective presentation of the type of contributions within the professional-amateur framework for the study of gaseous giants. In particular: The need for Professional-Amateur collaborations in studies of Jupiter and Saturn Emmanuel Kardasis, John H. Rogers, Glenn Orton, Marc Delcroix, Apostolos Christou, Mike Foulkes, Padma Yanamandra-Fisher, Michel…
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…
During the European Planetary Science Congress 2013 (Sep 8-13, 2013, London, UK) we presented the following work: Digital daylight observations of the planets with small telescopes Emmanuel (Manos) I. Kardasis Abstract Planetary atmospheres are extremely dynamic, showing a variety of phenomena at different spatial and temporal scales, therefore continuous monitoring…
