Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12715 has continued to grow in
the past 24 hours and is re-classified as beta/D-type sunspot group.
This region has produced several B-class flares and the largest event
since the last message, a C2.1 flare on 21-Jun-2018 at 01:09 UT. More
C-class flares are possible over the next 24 hours.
The position of NOAA 12715 on 21-Jun-2018 at 12:30 UT is:
N07E13, ( -212", 104" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12714 and the new flux
region in the North East quadrant showed signs of growth in the past
24 hours with the new region becoming designated as NOAA 12715. Both
are classified as beta/C-type sunspot groups, and both produced B1.8
flares since the last message. The target region will switch to NOAA
12715 as it appears to still be in its growth phase. No increases in
flaring activity are expected in the following 24-hour period.
The position of NOAA 12715 on 20-Jun-2018 at 14:00 UT is:
N07E24, ( -386", 91" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. A small flux region is emerging
in the North East quadrant and the leading part of a pre-existing flux
region is rotating over the North East limb (most likely the return of
the region previously numbered NOAA 12712). The target region has been
designated as NOAA 12714, with a beta/B-type sunspot group class. This
region has produced some low B-class events since the last message, the
largest being a B1.7 on 19-Jun-2018 at 05:34 UT. No increase in flaring
activity is expected in the next 24 hours.
The position of NOAA 12714 on 19-Jun-2018 at 12:30 UT is:
N08W48, ( 696", 115" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA region 12713 has stabilised,
regaining a beta/B-type sunspot group classification. This region was the
source of the only flare since the last message, a B1.1 on 17-Jun-2018 at
22:38 UT. A new small region is in the process of emerging to the west of
NOAA 12713 and will become the new target. No increase in flare activity
is expected over the following 24-hour period.
The approximate position of this region on 18-Jun-2018 at 12:00 UT is:
N08W33, ( 511", 113" )

Dear RHESSI Collaborators,
The largest event since the last message was a B1.3
at 13:21 UT on June 17 produced by the target region
NOAA 12713. 12713 also produced several high A-class
flares. 12713 has decayed to an alpha/A-type region. No
significant activities are expected in the next 24 hours.
The position of NOAA 12713 on June 17 at 16:10 UT is:
N05E05 (-82", 61")

Dear RHESSI Collaborators,
The target region NOAA 12713 (the only region with sunspots
on the visible solar disk) was the source of two A-class events
as well as a B1.6 flare at 05:16 UT on June 16. 12713 retains
its beta/B-type magnetic configuration. It has begun to decay.
Only very low level activities are possible over the following 24
hours.
The position of NOAA 12713 on June 16 at 16:10 UT is:
N05E20 (-323", 64")

Dear RHESSI Collaborators,
Solar activity continues at a very low level. The largest
event since the last message was a B1.1 at 06:46 UT
on June 15 produced by the target region NOAA 12713.
12713 also produced a B1.0 flare. 12713 remains its
beta/B-type configuration. Only very low level events are
possible in the next 24 hours.
The position of NOAA 12713 on June 15 at 16:10 UT is:
N05E33 (-514", 67")

Dear RHESSI Collaborators,
Solar activity has been at a very low level. No flares occurred
in the past 24 hours. The target region NOAA 12713 remains
its beta/B-type configuration but increasing in sunspot area and
number of spots. Only very low level activities are possible over
the next 24 hours.
The position of NOAA 12713 on June 14 at 16:10 UT is:
N06E46 (-677", 88")

Dear RHESSI Collaborators,
Solar activity continues at extremely low levels. No flares
occurred since the last message. The target region has
been designated as NOAA 12713. It has a beta/B-type
classification. Very low level activities are likely in the next
24 hour period.
The position of NOAA 12713 on June 13 at 16:10 UT is:
N03E59 (-810", 42")

Dear RHESSI Collaborators,
The target region was the source of a B1.1 and an A9.7 flares
since the last message. This region was unnumbered yet, and
is still too close to the limb to obtain its magnetic configuration.
It continues showing some EUV jets. B-class activities are likely
in the next 24 hours.
The approximate position of the target on June 12 at 19:30 UT is:
N05E74 (-880", 80")
