Radio Bursts Event List
Solar Radio Flux Data
Air Force 245, 410, and 610 MHz Data Resumes
April 4, 2010-- The 28ft radio antennas at all four Air Force RSTN sites:
Learmonth, Sagamore Hill, Palehua, and San Vito are operational.
IFLUX and BURST data at 245, 410 and 610MHz have resumed beginning with
Palehua on March 18th.
====================================================================
This directory contains a "Radio Burst Event List" for the last 45 days.
The event reports are from SWPC's preliminary solar event reports received
at SWPC and manually reviewed and edited by the duty forecaster. SWPC
compiles these lists from preliminary reports received from contributing
stations. Incorrect, missed, and incomplete reports are possible. Complete
daily event lists are available at
http://swpc.noaa.gov/ftpmenu/indices.html
or /pub/indices/ for FTP users.
The Radio Burst list is updated every 30 minutes at 10 and 40 minutes
past the hour.
A sample list and descriptions of each field are included below.
The format is fixed, 80 columns wide.

The first line is the filename.
The second line is the date/time the list was created.
All times and dates are UTC, Coordinated Universal Time.
Lines beginning with : or # are header lines.
Date - UTC date of the start time of the events.
Start, Max, End -
The UTC Time (Coordinate Universal Time, same as UT) of the start,
maximum, and end of the event as reported by the observing site.
"////" indicates a missing time.
The UTC day of the event's begin time is the UTC day of the list.
The UTC day of the maximum and/or end times may or may not be the same
as the begin time. Most solar events are several hours in duration. If
the maximum or end time is less than the begin time, then assume the
times are for the next UTC day.
A single letter can proceed a Start, Max, or End time.
A=after, B=before, U=uncertain.
For example the begin time A0146 means the event began after 0146.
Obs - The reporting observatory.

(See the "Station Lists" directory in the "Welcome" directory for
more information.)
Q - Quality
For radio bursts at fixed and sweep frequencies, and for storms, this
shows the quality of the data
C = Corrected report
G = Good
U = Uncertain
Type - Type of report, see http://www.swpc.noaa.gov/info/glossary.html
RBR = Fixed-frequency radio burst
RNS = Radio Noise Storm
RSP = Sweep-frequency radio burst
Freq - RBR and RNS -- Frequency in MHz
RSP -- Frequency rancge in MHz
Peak Flux or Sweep
RBR 245 or 2695 MHz. -- Peak value above pre-burst background of
associated radio burst.
1 solar flux unit = 10-22 Wm-2 Hz-1
RSP:
II/i nnn -- Type II: Slow drift burst
IV/i nnn -- Type IV: Broadband smooth continuum burst
i -- The intensity on a relative scale from 1 (low) to 3 (high) of
the sweep radio event associated with the energetic event.
Solar Wind Speed
nnn -- Shock speed in km/s for Type II bursts
Reg# - The SWPC-assigned solar region number. The daily SWPC Solar Region
Summary report contains detailed information about solar regions.

Old Notices
=== Air Force 245, 410, and 610 MHz Data Resumes ===
April 4, 2010-- The 28ft radio antennas at all four Air Force RSTN sites:
Learmonth, Sagamore Hill, Palehua, and San Vito are operational.
IFLUX and BURST data at 245, 410 and 610MHz have resumed beginning with
Palehua on March 18th.
March 31, 2010-- The 28ft radio antennas at Air Force RSTN sites at
Learmonth, Sagamore Hill and Palehua are operational. IFLUX and BURST
data at 245, 410 and 610MHz have resumed beginning with Palehua on
March 18th.
Repairs at the San Vito Italy RSTN site are expected to be completed
by April 15.
=== Air Force 245, 410, and 610 MHz Data Resumes ===
March 25, 2010-- Repairs to the 28ft antennas at all Air Force RSTN
sites (Learmonth, San Vito, Sagamore Hill and Palehua) should be
completed March 31. IFLUX and BURST data at 245, 410 and 610MHz resumed
from most sites this week, beginning with Palehua on March 18th.
SWPC did not receive 245, 410, and 610 MHz IFLUX or BURST data from
any RSTN site from March 5-17, 2010.
====================================================================
=== No Air Force 245, 410, and 610 MHz Data Until Further Notice ===
March 5, 2010 -- The Air Force RSTN sites (Learmonth, San Vito, Sagamore Hill
and Palehua) have taken their 28ft antennas out of service due to safety
concerns with the gearing mechanism that positions the antenna. Affected
frequencies are 245, 410 and 610 MHz. As a result, SWPC will not be receiving
IFLUX or BURST data from these three frequencies until further notice.
The estimate to repair the Learmonth site is at least 15 weeks. The other
sites may resume soon if they are not affected by the problem.
