Details About This Podcast
In this episode, Amateur Radio Operator, Tomas David Hood, NW7US, discusses the basics of Sporadic-E (Es), and talkes about the possible decline in sunspot magnetic energy that might mean no sunspots in 2015. Tomas also discusses the outlook for the rest of the year and Solar Cycle 24.
Additionally, the past week in space weather and propagation is reviewed, and the outlook for this coming week is presented.

The official keepers of sunspot counts, the SIDC in Belgium, reported today that a small sunspot (that they report as Catania #16) appeared late 30-July-2009:

# DAILY BULLETIN ON SOLAR AND GEOMAGNETIC ACTIVITY from the SIDC #
# (RWC Belgium) #
#--------------------------------------------------------------------#
SIDC URSIGRAM 90730
SIDC SOLAR BULLETIN 30 Jul 2009, 1302UT
SIDC FORECAST (valid from 1230UT, 30 Jul 2009 until 01 Aug 2009)
SOLAR FLARES : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 30 Jul 2009 10CM FLUX: 069 / AP: 006
PREDICTIONS FOR 31 Jul 2009 10CM FLUX: 069 / AP: 006
PREDICTIONS FOR 01 Aug 2009 10CM FLUX: 069 / AP: 003
COMMENT: The Earth passed the co-rotating interaction region of the
high latitude coronal hole. We expect only minor disturbances: K-index
of 2, maximum 3. A small sunspot popped up in the western part of the
solar disk. No flaring activity is produced. The all-quiet-alert is
still valid. |
Remember Catania #15? NOAA never assigned their number to that one. This is another sunspot of very small nature; it might develop into a larger region, or it may not. If not, NOAA may not assign a number to this one, either.
However, as I made the point last time: we're seeing 'something' more than a purely BLANK solar disc - more often than not, now. The activity level is, while still very low, never-the-less, increasing. If this trend continues, the latter part of 2009 may see a bit of an upward rise in overall solar activity, and hopefully, an uprise in ionization of the ionosphere. That means we may see an improvement in HF communications on higher shortwave frequencies over the conditions of these last few years.
By the way, if you look at the current solar disc - you'll see the remains of that big sunspot group 1024, in the southeastern area of the solar disc. It still has a bit of magnetic activity, but has spread into a rather large area.
See you on the bands!
