Request to Kevin Fetter: Is it possible for him to videorecord this object in a couple of transits east of the observer and a couple of transits west of the observer. note 2. 1983-022A (13923) NOAA 8 Optical pattern changed from irregular to regular. Irrgelar in this case means several relative maxima within a period that disappeared later in the transit. note 3. 1999-067A (25991) DMSP 5D-2 F15 Flash period suggests that this payload is still operational. note 4. 1973-086U (07028) NOAA 3 r deb The subsequent maxima showed a certain waving (undulation?) note 5. Period determined by counting the minima, as indicated by the comma in stead of the apostrophe. Secondary maxima occurred alternately. note 6. 1979-057A nnnnn In the beginning of my measurement all maxima were flashes evolving to round maxima at the end. flashy maxima: 11.16 [3.45 7.77] [3.81 2.99 4.79] rather round maxima: [6.75 5.15] [3.47 2.77 4.37] [6.72 4.80] [6.72 4.35] [4.00 3.22 4.24] [7.44(m 1) 40.6] [4.38 7.06] 11.53 [3.99 2.23 5.59] The URL explaning the format of PPAS observations : http://www.satobs.org/tumble/flashpm.html#PPASformat Bram Dorreman COSPAR 4160 51° 16' 45.5" N 5° 28' 36.6" E (WGS84) 35 m ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
