Ua hana ʻo Parker Solar Probe (PSP) i ka hōʻiliʻili ʻikepili in-situ a ua hopu ʻia nā kiʻi kokoke loa o ka Lā i kona hoʻokokoke kokoke loa ʻana i perihelion ma Kekemapa 2024. Ua hana ʻia kēia mau kiʻi a hoʻokuʻu hou ʻia ma ka lā 10 Iulai 2025. ʻO nā Coronal mass ejections (CMEs) he mau puʻupuʻu nui o nā ʻāpana i hoʻopaʻa ʻia he kumu nui o ka hopena o ka lewa ma ka Honua a ma ka lewa.
Ma ka lā 24 Dekemaba 2024, ua hoʻokokoke loa ʻo Parker Solar Probe (PSP) i ka Lā ma perihelion ma kahi mamao o 6.1 miliona km (no ka hoʻohālikelike ʻana, ʻo ka mamao ma waena o ka honua a me ka Lā he 152 miliona km) ma ka wikiwiki o 692,000 kmph (ka wikiwiki loa o nā mea i hana ʻia e ke kanaka). Ua hele ka ʻimi noiʻi i loko o ka corona (ka lewa waho loa o ka Lā) a hana i ka hōʻiliʻili ʻikepili in-situ a hopu i nā kiʻi kokoke loa o ka Lā me ka hoʻohana ʻana i nā mea kani like ʻole, me ka Wide-Field Imager for Solar Probe (WISPR). Ua hana ʻia a hoʻokuʻu ʻia kēia mau kiʻi i ka lā 10 Iulai 2025.
Hōʻike nā kiʻi WISPR kokoke loa o ka Lā i nā hiʻohiʻona o ka corona a me ka makani lā.
ʻO kekahi o nā kiʻi koʻikoʻi i hopu ʻia e ka ʻimi noiʻi ʻo ia nā hiʻohiʻona kokoke i ka hui ʻana o ka nui o ka coronal mass ejections (CMEs), ka nui o nā ʻāpana i hoʻopaʻa ʻia he mea hoʻokele nui o ka lewa. Ke kuʻi nā CME, hiki ke loli ko lākou alahele, ʻoi aku ka paʻakikī o ka wānana i kahi e pau ai lākou. Hiki i kā lākou hui ʻana ke hoʻolalelale i nā ʻāpana i hoʻopaʻa ʻia a hoʻohui i nā māla magnetic, kahi e ʻoi aku ka pōʻino o nā hopena CME i nā astronauts a me nā satelite i ka lewa a me ka ʻenehana ma ka honua. ʻO ka ʻike pili kokoke a Parker Solar Probe e kōkua i ka poʻe ʻepekema e hoʻomākaukau maikaʻi no kēlā mau hopena lewa ma ka Honua a ma waho.
He mea nui ka hoʻomaopopo ʻana i ke kumu o ka makani lā no ka hoʻomaopopo ʻana i kona hopena i kā mākou enprises e pili ana i ka lewa a me nā ʻano ola a me nā ʻōnaehana ma ka Honua. Hāʻawi nā kiʻi hou i ka nānā pono ʻana i ka hopena o ka makani lā ma hope koke o ka hoʻokuʻu ʻia ʻana mai ke corona. Hōʻike lākou i ka palena koʻikoʻi kahi e hoʻololi ai ka ʻaoʻao o ka lā mai ka ʻākau a i ka hema, i kapa ʻia ʻo ka heliospheric current sheet.
ʻO nā hiʻohiʻona kokoke e hiki ai iā mākou ke hoʻokaʻawale i ke kumu o nā ʻano ʻelua o ka makani lohi o ka lā - Alfvénic (me nā hoʻololi liʻiliʻi liʻiliʻi) a me ka non-Alfvénic (me nā ʻano like ʻole o kāna kahua magnetic). Hiki mai paha ka makani Alfvénic mai nā hiʻohiʻona i kapa ʻia he mau kahawai mahiole (nā puka lou nui e hoʻopili ana i nā wahi ikaika kahi e wela ai kekahi mau ʻāpana e pakele ai) akā hiki mai ka makani Alfvénic ma kahi kokoke i nā lua coronal, a i ʻole nā wahi ʻeleʻele a anuanu o ke korona.
ʻO ka makani Solar, ʻo ke kahawai mau o nā ʻāpana subatomic i hoʻokuʻu ʻia i ka uila i hoʻokuʻu ʻia mai ka Lā e laha ma ka ʻōnaehana solar i ka wikiwiki ma mua o 1.6 miliona kmph he ʻelua ʻano - wikiwiki a lohi. Hoʻohana ʻia ka makani lā wikiwiki e ka hoʻololi ʻana (zig-zagging magnetic field i nā puʻupuʻu i ʻike pinepine ʻia ma ka corona). Holo mālie ka makani lā ma ka hapalua o ka māmā o ka makani lā wikiwiki (=355 km kekona). ʻOi aku ka pālua o ka mānoanoa a ʻoi aku ka loli ma mua o ka makani lā wikiwiki. Ma muli o ka hoʻonohonoho ʻana a i ʻole ka hoʻololi ʻana o kā lākou mau mākēneki, ʻelua ʻano ʻano makani lohi o ka lā – Alfvénic, loaʻa nā hoʻololi liʻiliʻi a me ka Alfvénic ʻole, ʻaʻole ia e hōʻike i kēia mau ʻokoʻa i kāna māla magnetic. He mea nui ke aʻo ʻana i ka makani lohi o ka lā no ka mea hiki i kāna pilina me ka makani lā wikiwiki ke hana i nā ʻano ʻino o ka lā ma ka Honua.
Lele ʻo Parker Solar Probe (PSP) i loko o ka lewa o ka Lā ma 6.2 miliona km i ka Lā ma kahi kokoke loa, e hana ana i nā ana ma kahi e ʻike ai i ke kahe ʻana o ka ikehu ma ke corona. Hana ʻo Solar Orbiter (SO), ma kahi ʻē aʻe, i ka nānā ʻana ma kahi a me kahi mamao ma 42 miliona km i ka Lā ma kahi kokoke loa. Ke aʻo nei ia i ka photosphere, ka lewa o waho a me nā loli i ka makani lā. I kēia mau lā, ua kiʻi ʻo Solar Orbiter i nā kiʻi mua loa o ka pole hema o ka Lā no ka hoʻomaopopo ʻana i ka hana a ka Lā a me ka pōʻaiapuni o ka lā i kona lele ʻana i Malaki 2025. Ke hana nei ʻo Parker Solar Probe (PSP) a me Solar Orbiter (SO) i ka lewa e wehe i ka hana o ka Lā a me nā kaʻina kumu e alakaʻi ai i ka lewa ma ka Honua.

 made in-situ data collection and captured closest ever images of the Sun during its last closest approach at perihelion in December 2024. These images were processed and released recently on 10 July 2025. Close –up views of collision of multiple coronal mass ejections (CMEs) taking place in outermost solar atmosphere is one of the most important images captured by the probe. Coronal mass ejections (CMEs) are large outbursts of charged particles that are a key driver of space weather effects at Earth and in space.){kind=link}
