The PSP mission’s 28th Encounter will be occurring between June 3 - 13, 2026. Perihelion 28 will be occurring on June 8, at about 04:35 UT. Prior to perihelion, Parker Solar Probe will be connected to far side sources. At the time of perihelion, the spacecraft will be approximately on the plane of sky as seen from Earth over the solar East limb. The footpoints will then rapidly advance on disk for a few hours after perihelion and proceed over the disk with footpoint motion gradually decelerating. Footpoints will reach the central meridian around 6/9 23:00 UTC and will then proceed slowly towards the West limb over the remainder of the month. In support of the above projections, Parker footpoint daily predictions will be issued daily from Sunday, June 7 to Thursday, June 11.

TODAY'S TARGET: Encounter 28 Prediction update 5/5: 2026/06/11
------------------------------------------------
This is the last of five daily footpoint predictions issued for Parker Solar Probe Encounter 28, Parker's 7th perihelion at 9.86Rs. Perihelion 28 occurred on Monday 2026/06/08 at 04:35 UT (00:35 EDT). For its inbound orbital phase, Parker was on the solar far side. Today the spacecraft continues to be connected stably to a transequatorial coronal hole now westwards of the central meridian and is predicted to remain in that coronal hole's stream through the outbound phase of the orbit.
Magnetic Connectivity
---------------------
Footpoint predictions remain stable connecting to the southern latitude interior of a negative polarity, transequatorial coronal hole, which is the most prominent equatorial hole visible on disk right now, lying just westwards of the central meridian (SolarMonitor.org.
Beyond today, footpoints remain embedded deep in this coronal hole and track with it across the solar disk until at least 2026/06/15, and potentially all the way until 2026/06/17 (just after the coronal hole passes over the western limb). The angular speed of Parker will then have decreased sufficiently at this point for the footpoints to be outstripped by the coronal hole's continued rotation, and will trace back through the Eastern edge onto other near East limb sources.
Further note: After appearing to become less coherent in yesterday's magnetograms, the structure of the HCS around perihelion has reverted back to its prior state and in this last update we predict Parker should pass through two current sheets just before and after perihelion, with positive polarity during closest approach.
Flare Likelihood (CCMC Flare Scoreboard)
----------------------------------------
As of 2026/06/11 at 12:00 UT, the ISWA CCMC Flare Scoreboard reported 24-hour average cumulative probabilities of 95%, 35%, and 3% for GOES C and above, M and above and X-class flares, respectively. These are slightly lower than in yesterday’s update. The strongest flare reported over the past 24 hours was a GOES C9.0 event peaking at 08:22 UT on 2026/06/11 and stemming from NOAA AR 14465. NOAA active regions visible on the disk include ARs 14459 and 14461 - 14466. All except NOAA ARs 14461 and 14464 are located in the northern hemisphere. The small transequatorial coronal hole to which Parker is magnetically connected since shortly after perihelion has rotated further to western longitudes.
From the CCMC CME Scoreboard, there are apparently four Earth-directed CMEs: (1) one with a near-Sun speed of 270 km/s launched on 2026/06/08 at 06:12 UT from the vicinity of NOAA AR 14464; (2) one launched on 2026/06/09 at 16:36 UT from the vicinity of NOAA AR 14463 with a near-Sun speed of 380 km/s; (3) one launched on 2026/06/09 at 21:36 UT from the vicinity of NOAA AR 14461 with a near-Sun speed of 348 km/s; and (4) one launched on 2026/06/11 at 00:36 UT from the vicinity of NOAA AR 14465 with a mean near-Sun speed of approx. 890 km/s. While the first is expected to reach geospace around 2026/06/11 at 20:00 UT with up to a minor geomagnetic event expected, the other two CMEs are expected to both arrive early on 2026/06/13, at 01:00 - 02:00 UT. Each of them is separately expected to give rise to no more than a minor geomagnetic event (Kp ≤ 5), but a potential superposition of both events may lead to nonlinear effects and possibly a stronger geoeffectiveness. The most recent CME event is expected to reach geospace on 2026/06/13 with time of arrival spanning between approx. 09:10 UT and approx. 16:13 UT, depending on the forecast model. This CME could trigger up to a strong geomagnetic event (Kp ≤ 5). Events 2 - 4 are likely to influence Parker’s in situ measurements given their propagation toward Earth.
