This report concerns radio meteor counts for an observing station in Salt Lake City for the period: Date-UT MJD Solar Longitude 2010-Feb-01 00:00 55228.5 312.0 2010-Feb-28 23:59 55256.5 340.2 based on reflections at frequency 55.250 mhz CW (VHF Channel 2). Daily counts are appended and plots can be viewed graphically at: 2D Plot http://www.slas.us/gallery2/main.php?g2_itemId=3089 3D Plot http://www.slas.us/gallery2/main.php?g2_itemId=3087 Directory with data csv and graph files http://www.slas.us/gallery2/main.php?g2_itemId=2970 Recorded meteor reflection counts can be downloaded from: http://www.slas.us/gallery2/main.php?g2_itemId=3094 http://www.slas.us/gallery2/main.php?g2_itemId=3091 A value of "0" in the csv file (itemID-3094) means the station was down and not recording during the indicated hour. A maximum monthly hour count of 109-110 was recorded on Feb. 1 10UT-11UT and of 117 on Feb. 2 at 16UT-18UT. No significant meteor shower activity is expected until the April Lyrid shower and in general February's counts were consistent with a normal apex-of-way background count. There was a mild elevated level and peak recorded during first week of February. These elevated counts were consistent with an International Meteor Organization suggestion of a Capricornids/Sagittariids peak on Feb. 1 at 15UT: "The late January to early February spell, during which several new, swift-meteor, minor showers, radiating from the Coma-Leo-Virgo area have been proposed in some recent years, enjoys a waxing Moon for its potential core period, January 20-27. Theoretical approximate timings (rounded to the nearest hour) for the daytime radio shower maxima this quarter are: Capricornids/Sagittariids - February 1, 15h UT; ; and ksi-Capricornids - February 13, 16h UT.. .. ." . .. ." IMO 2010 Calendar url: http://www.imo.net/calendar/2010 . The recording station also captures a spectrograph covering a 20 minute time period between 40 and 59 minutes of each hour. As discussed below, spectrographs recorded ionic disturbances during this month. February saw the return of sunspot activity. From Feb. 8 to Feb. 11, a series of eruptions occured from behemoth sunspot 1045 that generated a series of M-class flares and Type III radio bursts (at 10,000 to 100,000 Hz). http://www.spaceweather.com/archive.php?view=1&day=08&month=02&year=2010 The NOAA Spaceweather System reported radio 10cm radio bursts on Feb. 11, peaking at 14:16UT. http://www.swpc.noaa.gov/ftpdir/lists/radio/radio_bursts.txt As Sunspot 1045 waned, on Feb.12 through the 16th, sunspot 1046 grew and also generated M1-class flares. Two CME's emitted by Sunspot 1045 were directed away from the Earth on Feb. 15 and 16. http://www.spaceweather.com/archive.php?view=1&day=12&month=02&year=2010 http://www.spaceweather.com/archive.php?view=1&day=14&month=02&year=2010 http://www.spaceweather.com/archive.php?view=1&day=20&month=02&year=2010 Around Feb. 19 through Feb. 22, a solar filament formed on the Sun's disk, ending in a subdued Hyder flare when the filament disconnected on Feb. 24. http://www.spaceweather.com/archive.php?view=1&day=21&month=02&year=2010 http://www.spaceweather.com/archive.php?view=1&day=25&month=02&year=2010 (It at the time of this posting (March 7), a new large solar filament has formed. http://www.spaceweather.com/archive.php?view=1&day=07&month=03&year=2010 ). A significiant ionic atmospheric distrubance was recorded on Feb. 11 between 01 and 03 UT and on Feb. 14 04UT. Spectrograph 20100211 02UT (Associated with NOAA 10cm (245MHz) radio burst) http://www.slas.us/gallery2/main.php?g2_itemId=3079 Spectrograph 20100214 04UT (No NOAA 10cm (245MHz associated radio burst) http://www.slas.us/gallery2/main.php?g2_itemId=3081 Many smaller ionic distrubances were recorded throughout the month. A representative example occured on Feb. 16 at 09UT. Spectrograph 20100216 09UT http://www.slas.us/gallery2/main.php?g2_itemId=3085 Since the antenna used is omni directional, the location of the source transmitter(s) is unknown. On Feb. 14 at 17UT, an artificial reflector was recorded. The parabolic trace is interperted as an airplane passing almost directly over a transmitter site. Spectrograph 20100214 17UT Airplane reflection trace http://www.slas.us/gallery2/main.php?g2_itemId=3083 On Feb. 23 at 13:07UT, a test was run to determine if the International Space Station (ISS) would act as a reflector that could be recorded by this station. The ISS overflight - with a peak visual magnitude of -3.9 and at an observer-to-target distance of approximately 516km - that occured at that time was simulatenously recorded using an all-sky meteor camera and by the meteor radio reflection station. No radio reflection was recorded.
