This bulletin is a compilation of currently active DX operations (or those that will become active within the current week) from recent issues of the three DX bulletins listed below and other sources. Credit for the source is given at the end of each article.
Articles are ordered by the entity's callsign prefix from the ARRL DXCC Entities List. Callsigns used are in bold with dates of operation highlighted in red. Clickable links are provided for QSL and other information wherever possible. Note that articles may be edited for grammar, language, style and accuracy and will remain in The Bulletin while active; articles that are announcements of ongoing operations, or that have no specified end date, will be removed after three weeks.
Also included is a Propagation section, updated daily; and a Contest Calendar of upcoming popular contests.

announced on June 20th that LoTW
will receive a major upgrade as part
of the modernization of ARRL computer systems. LoTW will receive
upgrades to the operating system, database system, and server hosting,
where it will be migrated to the cloud. These changes will ensure LoTW
performance meets future user demand.
LoTW will be unavailable from June 27th to
July 2nd. It may
come back before July 2nd if the upgrade
is completed earlier than anticipated.
Please see the ARRL website at https://www.arrl.org
for complete details.

Summary
For the 8 day period from Sunday, June 15th through yesterday, June 22nd.
The average solar flux was 134, down 7 points from the previous week,
with a weekly high of 161 on Sunday, June 15th, followed by
a low of 120 on June 21st.
The average sunspot count was 102, down by 19 from last week,
peaking at 141 on Sunday, June 15th followed by a
weekly low of 80 on June 22nd.
The Planetary K-index weekly average was 3.5 with a
maximum of 4.3 on Thursday, June 19th, indicating
generally quiet geomagnetic conditions. Yesterday's K-index maximum was 3.7 continuing the generally quiet conditions.
Solar flare activity since June 16th has been decreasing with 7
major flares, the largest of which was a major X 1.9 event on Thursday,
June 19th.

A Hole in the Sun's Atmosphere
A large hole in the sun's atmosphere
is turning toward Earth and spraying a stream of solar wind in our
direction. The leading edge is expected to arrive late on June 25th,
bringing a chance of G1-class
geomagnetic storms. High-latitude sky watchers should be alert for
auroras, especially in the southern hemisphere where winter darkness
favors visibility.

Global
D Region Absorption
Conditions in the D-region of the ionosphere
have a dramatic effect on HF communications. The D-Region Absorption
map combines the effects of solar particles and
photons. Yellow to red colors on the map depict increasing signal
attenuation, where the bar chart at the right displays attenuation
versus frequency. Click the
thumbnail below for an animated map of D-Region Absorption:
The Aurora
Borealis
The aurora is not only beautiful to see but can have a
profound impact on HF and VHF radio propagation. For the HF operator,
auroras can result in a complete shut-down of propagation. However, on
VHF, auroras present interesting DX possibilities. Beam antennas are
very desirable and should be pointed north, towards the aurora. Signals
are reflected by “back-scatter” and will be distorted with a rough
buzz. SSB is the best voice mode to use, but copy can be difficult. CW
will have a rough buzzy sound but be perfectly copyable. Click the
thumbnail below for an animated map of aurora versus time:

A Propagation
Tutorial
The solar X-ray flux tracks solar activity and solar flares.
Solar
flux, which can vary from as low as 50 to as high as 300, influences
the level of ionization in the F2 region of the ionosphere, providing a
very good prediction of HF DX conditions. The higher the solar flux,
the better conditions will be for the higher HF frequencies and even 6
meters. However, the levels need to be maintained for some days to
allow ionization in the F2 layer to build up. A solar flux of 150
results in good HF band conditions, while levels of 200 and up can
provide great conditions.
Large X-ray flares on the sun can
increase the ionization of the D layer of the ionosphere (a lower
layer) on the sunlit side of the Earth, greatly attenuating or blocking
HF radio transmissions for up to a half hour. Solar flares often
produce Coronal Mass Ejections (CMEs) which, if Earth directed, can
lead to geomagnetic storms. Some large flares are also accompanied by
strong radio bursts that may interfere with other radio frequencies and
cause problems for satellite communication and radio navigation (GPS).
The
Planetary K-index is a measure of the magnitude of geomagnetic storms
and is an excellent indicator of disturbances in the Earth's magnetic
field. A level of 1 or 2 represents quiet geomagnetic conditions; a
reading of 3 or 4 may cause some propagation deterioration; 5 and 6 are
minor to moderate geomagnetic storms; and 7 to 9 are strong, severe,
and extreme storm conditions. Strong geomagnetic storms can trigger
Auroral displays and cause HF radio blackouts. Higher geomagnetic
activity also has the adverse effect of lowering maximum usable
frequencies, much like lower solar flux does.
For
best conditions, the solar flux should be above 150 for a few days with
the K index below 2. When these conditions are met, some good DX is
likely!
