Κυριακή 23 Ιουνίου 2013. Από την παραλία του Αγίου Μάμα της Χαλκιδικής, η υπερσελήνη ανέτειλε, πάνω από τον Τορωναίο Κόλπο, στο ύψος της μικρής νήσου Κέλυφος, που βρίσκεται ανοιχτά του Ν. Μαρμαρά Χαλκιδικής. Canon350D. Canon Lens:35-80. F.L.:80mm. F:6,3. Exp. 1sec.

Τελικά μπαμπά, το μεγαλύτερο φεγγάρι της χρονιάς, δεν είναι και τόσο μεγάλο!

Καθώς ο διάσημος κομήτης απομακρύνεται από τον ήλιο, υστερεί συνεχώς σε φωτεινότητα, (τώρα με μέγεθος περίπου 8.5) παραμένει όμως εντυπωσιακότατος, καθώς, η αντί-ουρά του εκτείνεται σε εύρος αρκετών μοιρών, του νυχτερινού ουρανού, στον αστερισμό του Κηφέα. Εδώ με κέντρο τον αστέρα SAO3794 του Κηφέως.

Spacetrack catalog number 38758 COSPAR ID 2012-048-A Name in Spacetrack catalog USA 238 Orbit 1,025 x 1,188 km, 63.4° Country/organitisation of origin USA Intrinsic brightness (Mag) 3.7 (at 1000km distance, 50% illuminated) Maximum brightness (Mag) 3.8 (at perigee, 100% illuminated) Info: http://www.heavens-above.com/satinfo.aspx?l NROL-36 ------- On Sep 13 United Launch Alliance flew a Lockheed Martin Atlas V 401, serial AV-033, from Vandenberg Air Force Base. The main payload is thought to be a pair of Navy signals intelligence satellites deployed in a 1010 x 1200 km x 63.4 deg orbit after the second Centaur burn. (The primary satellite is USA 238; the secondary satellite has not yet been cataloged and may not have separated yet). This series of satellites is thought to be the modern successor to NRL's GRAB/POPPY/PARCAE satellites, first launched in 1960. The Centaur then made two further burns to 470 x 780 km x 64.7 deg. The Centaur second stage carries the OUTSat secondary payload which ejected 11 small 'cubesats,' for a mixture of US military and university customers. Of particular interest is CXBN, a Morehead State U. experiment to produce an all-sky 30-50 keV hard X-ray cosmic diffuse emission map. The two US Army sats in the SMDC-ONE (Operational Nanosatellite Effect) program are variously numbered 1.1/1.2 and 2.1/2.2 in different sources. The OUTSat structure is the NPSCUl launcher developed by the US Naval Postgraduate School. It contains 8 P-POD cubesat deployers which ejected the individual cubesats, a mixture of 1U (0.1m cube), 2U (0.1 x 0.1 x 0.2m box) and 3U (0.1 x 0.1 x 0.3m box) payloads, as follows: Pod 1 3U SMDC-ONE 1.2 (US Army Space and Missile Defence Command, Huntsville, Alabama) Comms Pod 3 3U Aeneas (U. Southern California, Los Angeles and Dept. of Homeland Security) Cargo container tracking Pod 4 3U CSSWE (U. Colorado, Boulder) Colorado Student Space Weather Expt. Radiation belt electrons and protons Pod 5 1U CP5 (Cal Poly. State U., San Luis Obispo) Solar sail deorbit technology 2U CXBN (Morehead State U., Morehead, Kentucky) Cosmic Hard X-ray background Pod 6 3U CINEMA 1 (U Cal. Berkeley) Magentospheric studies Pod 7 3U Re (Lawrence Livermore Natl. Lab, California) Space debris tracking Pod 8 3U SMDC-ONE 1.1 (US Army Space and Missile Defence Command, Huntsville, Alabama) Comms Pod 2 1U Aerocube 4 (Aerospace Corp., El Segundo, California) 1U Aerocube 4A (Aerospace Corp., El Segundo, California) 1U Aerocube 4B (Aerospace Corp., El Segundo, California) The payloads were ejected in the order Pod 1,3,4,5,6,7,8,2. I believe the OUTSat remained attached to the Centaur; whether you count it as an attached secondary payload or a non-payload piece of hardware is a matter of taste, but I'll count it as a payload. Since their first flight in 2003, 102 Cubesats have been launched: 2 suborbital, 19 launch failures (4 exoatmospheric), and 81 orbital. Of these, 60 are still in orbit. This includes two attached pairs, M-Cubed/E1PU2 and STARS-1, and five cubesats currently aboard the Kibo module which should be deployed later this month.

Δεν είναι σπάνιο, αλλά είναι σίγουρα ιδιαίτερο φαινόμενο, σύννεφα στο παρασκήνιο να δημιουργούν σκιές, στο ηλιοβασίλεμα, εδώ με φόντο το βουνό Πάικο, από το ερασιτεχνικό μου αστεροσκοπείο στον Άσπρο Κιλκίς Δ.Δ.Δήμου Παιονίας.
